Sometimes STOP is also used to force the loop to end. How END works behind the scenes: In this case, the calculator is told to save into the variable. Since Basic is such a slow language,. However, unlike FOR, WHILE does not automatically add one to the value of a variable each time around; you must tell it to add or subtract a certain amount. This makes it more flexible of a loop. While Y is less than or equal to 16, make the value of X equal to 1.
Add 1 to the value of X and repeat until X hits 8, at which point continue the outer loop and set X back to 1. Also add 1 to Y. Therefore, this column of X's is displayed over and over again, with the Y becoming 1 larger each time a column is completed, until Y hits 16 and the program ends.
If you code While 1, the operation within this while loop will be repeated forever, unless a command is in place to stop it, for example if the user presses ENTER then the loop stops. If you code While 0, the code between this and End will not execute. This is because computers rely on bits, tiny jolts of electricity, to transfer information. A small voltage stands for 1, and no voltage stands for 0.
Therefore, 1 stands for True, because there is a current present, and 0 stands for False, because there is no current. A good way to represent this is a light switch: when it's on, there is a current, and when it's off, there is no current.
So when you code While 1, what you are actually saying is While True. Compare This Following is an example for a bit more advanced use of the FOR function, you will find yourself using this much more often than the previous bit of code.
Some of the other functions used here are explained later in this tutorial. These programs are exactly the same visually, although what really goes on behind the scenes is drastically different. Please run all three of these programs on your TI, in order to see the differences e. I will try my best to explain the behavior of these programs.
A circle is drawn at the coordinates 0,0 in the center of the screen. Its radius is set to 0. The text "DONE" is then displayed. While X is less than 50, A circle is drawn at the coordinates 0,0 with a radius of X. When this happens, 'DONE' is displayed. The following is assigned to frame 1: a circle is drawn at 0,0 with a radius of X.
If X is equal to 50, the calculator is told to scan the program for a frame labeled 2; otherwise scan for a frame labeled 1 and go there. The OR command compares the value to many variables. It only searches for half of the factors, while the others are derived from the factors already found. FactorGhost This is the same as my Factor program, except it runs behind the scenes, and can be used from inside other programs. Factoring This program will produce factor pairs for a positive integer.
Great for algebra students. Factoring Program Factors positive integers. Take a look! Factoring This program asks you a number. It then finds all the factors for that number low RAM makes it not go as high.
While it checks for factors, It displays what percent done it is at the top. You will be able to view the factors in L6 Stat, edit, and look at L6.
Speed Factoriser A blazingly fast routine finds the prime factors of any integer. Simple Factor It! A very easy program to use that will give you all the factors of the input along with the squared value. Factorizer This program factors integers, decimals, and polynomials.
Find Factors This program finds all of the factors of a number. If you need any help, please let me know at stephenafinley gmail. It is basically a very fast prime factor program which does the prime factors and the divisors at the same time. The factor pairs are then extracted from the list of divisors. So it's very fast for what it does. Prime Factorization Program Finds the prime factorization of any positive integer. Factor Finder Finds all the factors of a number.
Uses a fast algorithm that will speed up factor finding once it has found half of the factors. Then it will find the rest of the factors using the existing factors. Prime Factors Finds the prime integer factors of a number. Fast and efficient. Factors X This program is used to find all the whole-number factors of a given integer. Input the number in the main screen, and in the graph screen, the program will show you what can divide into that number, and how many times.
Prime Factorization This program computes the prime factorization of a given number. It performs this computation pretty fast. As you can see from the screenshots, the display is really cool. This updated version changes the output for the program.

Factor Finds the integer factors of a number. Fast Prime Factorization Sometimes it's very useful to know a number's prime factorization.
This program will take an integer you enter and break it down into its prime factors, and it will do this very quickly. Factorization This Program will find the factors of an integer, the prim factors of an integer, checks an integer for being prim, factorizes quadratic equations and reduces square roots. All functions are fast and esay to access. The program is only bytes. Check if number is prime This program was made by David Gomes and shall not be released without his permission.
Thanks Zeda for optimizing it! Speed Prime A fast routine to test the primality of a number. Will tell you its smallest factor if it is composite. Factor This is a great program for school. It figures out the factors of numbers. It shows you the ones it figures out as it goes along and then lets you scroll thorough them when it's done. Just don't put in huge numbers, like , or it will take forever! Modular Factoring 1 This program finds the factors of any positive integer.
It takes about 10 seconds to determine that 1,, is prime, and about 3 seconds to find the factors of 1,, Modular Factoring 2 This program finds the factors of any positive integer. It takes about 7 seconds to determine that 1,, is prime, and about 2 seconds to find the factors of 1,, Briefly tested one composite seven digit number vs.
Number Factorer Really useful number factoring program. Prime Decomposition Using a combination of divisibility tests and methods inspired by fermat factorization, this program can find the prime decomposition of a number with remarkable speed and efficiency. Fermat factorization is usefull for factoring large numbers that are known to be the product of two primes relativly close to the square root.
This updated version is more memory efficient than the original. Prime Factors Find the prime factors of any positive integer. Prime Factorization 1. This takes around 25 minutes. Prime Number Generator The program will test a nubmer for being prime or generate a list of primes up to primes. Will test prime numbers 2 to The Prime Number Tester allows you to enter in any number, and it will tell you whether that number is prime or not.
The time it takes depends on how big the number is. You then have the option to factorise that number or not. The factorising algorithm isn't particularly fast, but it does work, if you are willing to wait for it. I wouldn't recommend trying to factorise anything over 3 digits, beacause it will take a long time and most likely run out of memory.
The Prime Number Lister allows you to create a list of prime numbers up to a number that you specify. The only limit on how many primes you can generate is the amount of memory your calculator has. The Lister will also store the primes into a list for you to work with. I have also fixed another glitch where if the lower factor of a number is an even number greater than two, the factor and its pair would not appear in the list of factors.
If you are not using the latest version, please update! Porc PORC is a program that you can use to test and see whether a number is prime or composite. The only downfall to this program is that the larger your number is, especially if it is prime, it takes the calculator longer to tell you whether the number is prime or composite. This program however works really well with the numbers that I use!
Possible Factors This program show all factors to get the number you put in. It display, too, if it's a prime. Probabilistic Primality Test This program is based on Fermat's theorem. If P fails for any base than it is composite. If P passes than it is probably prime. A prime will pass for all bases. The program can handle numbers up to around Under bytes. PrimeFactor This was so fun to make. This will tell you the prime factors of any number you put in.
Obvious, big numbers [telephone numbers. Email me if you have any problems. Primality Tester My first program, it checks whether or not a number is prime or composite; in other words, its primality.
Amazing Prime Number Generator This amazing machine will generate a list of prime numbers faster than any other program on the market.
It's a great way to pass countless hours in math class! If you don't believe me Unlike other programs, this one has been tested extensively and is made for convenience. Prime Tester v1. Yeah do the square roots go over all the numbers or just put the symbol with no numbers underneath?
I don't quite know if I understand what you mean by that? Could you maybe give me a reference on which line of code you're referring to? Reply 1 year ago. HI, I have a question for you. I copied your code, but I am having a display problem.
How do i fix this? Soooo, turns out - my code was riddled with issues it was super annoying to trouble shoot. However, I have fixed the code since I last posted it and now it seems to be working flawlessly. The output isn't always the prettiest, but I went for function of aesthetics. I entered it line by line, and this is the error code i got when i tried to run it I am wondering if that space in line 7 is needed?
Disp " Quadratic"," Solver","" you have a space in between the " and Quadratic" The first time I entered the code, I tired to copy and paste, and it gave me the same error, but had the option to "go to" pic 2. When I go to it is on the PlotsOff which is not highlighted in the next pic. I dont know why it does that when its copied. I honestly have no clue about programing, wish I had actually paid attention back in the days of DOS. I appreciate the effort you made. Thanks again.
No, those spaces inside the quotations are strictly there for alignment purposes just for the aesthetic of the program. Certain commands, however, need to have a space placed after them in order for it to function properly. Question 1 year ago. Is there a way to write this for equations that start cubed? Differently, is there a way to write it for a D variable as well? Tip 1 year ago. Hi everyone, this was a class project me and two other students had to do in college two years ago.
