Questions tagged [ti-basic]

TI-BASIC is the official name of a BASIC-like language built into Texas Instruments (TI)'s graphing calculators, including the TI-83 series, TI-84 Plus series, TI-89 series, TI-92 series, TI-73, and TI-Nspire. The capability to write programs in TI-BASIC is automatically built-in to Texas Instruments calculators.

Forms of TI-Basic

TI-Basic comes in three distinct forms, TI-83, 68K, and TI-NSpire. While these forms have much in common, they also have noticeable differences that make code written for one from almost completely incompatible with the others. For this reason it is important to explicitly state the form of TI-Basic you are using in any questions.

  • TI-83 Basic
    This is the most common form of TI-Basic. It refers the form of TI-Basic found on both TI-83 and TI-84 series of calculators. Even within this form of TI-Basic, there are variations in the availability of functions between calculators.
  • 68K
    This form of TI-Basic is far less common than TI-83 Basic. 68K TI-Basic is found on the TI-89, TI-92 and Voyage 200 calculators.
  • TI-Nspire
    Generally the least common form, this is only found on TI-Nspire series calculators. Due to the far superior processing power TI-Nspire calculators have, this form could have more potential than the others, but limitation in regards to input and output renders this form largely unused.

find sublist within larger list on a TI-84+

I'm making snake using the TI basic on my calculator, and that works well and all. the sublist would always be 2 long. I am aware of: max(not(L1-X)) but this only checks for 1 value and I need to check for the sublist {X,Y} not just X... the issue…

Trying to type '→' with keyboard module

I am making a program that writes a program in TI-Basic. In TI-Basic, to set a variable, the syntax is value → varname. The TI-Connect software doesn't like it when I copy-paste, so I'm using the keyboard module to simulate keypresses. I can't…

Is it possible to make a true random number generator in TI-Basic?

Is there any way on the TI-84 calculators to create a "true" random number generator? I know the one built into the calculator is a pseudo-random number generator but is it at all possible to create a true RNG so that no matter what the user wants…

JS: Replace a number with trailing zeros to scientific notation

I am creating a website that inputs code in TI-BASIC (a built-in, somewhat crappy programming language on the TI-83+/TI-84+ calculators) and attempts to optimize it. One common optimization is to replace, say, 10000 with 1e4, (more examples: 5500000…

TI BASIC remainder() domain error

In my TI BASIC program on TI 84 plus C, I have a line that says remainder((A/X),2). This creates a domain error every time the program runs. In the case of my tests, A/X is 4. remainder(4,2) works. 4->Z remainder(Z,2) works. If I pause the program…

Testing if value is in list/array (Ti-Basic)

Is there a way to test if a value is in a list? In Python, I think you can do something like 'if n in myList: print("Value N is in the list.")' I don't want to use a for loop to check each value seperately, unless it's the only option. I'm using a…
