Type validation

We're glad you came by, but you might find what you're looking for elsewhere. TI-Basic Developer is not the site it once was. While its information on commands and other calculator features remains almost second-to-none, its forum, archives, and even hosting service, Wikidot, have been decaying for years. The calculator community would love to see what you're working on, or help you in your next coding adventure, but TI-Basic Developer is no longer the place to do it. Instead, you should head over to Cemetech (primarily American) or TI-Planet (primarily international). Both are active, well-established forums with their own archives, chatrooms, reference material, and abundant coding tools and resources. We'll see you there, we hope.

Trying to figure out how to validate different variable types without throwing errors

Type validation

undeadf0x 16 Apr 2025 14:09

I just recently got into TI-Basic programming, and I've already ran into a problem!

The goal: To be able to take a variable, and then return a 1 (true) or 0 (false) based on if the variable type is the type we're checking for.

Strings (Unsolved)

Strings are the main reason this problem came up at all for me, and the reason I'm making this post. I've had a couple ideas for this, but so far they all lead to errors! My first thought was to try toString(Ans)=Ans, however this returns ERROR: DATA TYPE. I've tried some other ideas, such as checking for Length(, but without the Try command, we can't handle any of these solutions properly in TI-83 Basic.

Lists (Untested)

Matrices (Untested)

Numbers (Untested)
