The toString( Command

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.

The toString( command, given any value including real numbers, complex numbers, lists, or matrices, returns the string representation of the value of the input.

toString(1337       //returns "1337"

toString({1,2,3}    //returns "{1,2,3}"

toString([[1,2][3,4]]   //returns "[[1,2][3,4]]"

toString(√-1     //returns imaginary number "i"

toString( has less limitations than the eval( command. It can handle lists, matrices, and complex numbers. Another difference from eval( is that toString( is affected by display mode changes like Fix.

toString( replaces the old number-to-string routine previously used prior to OS 5.2.

Error Conditions

• ERR:DATA TYPE is thrown when the input is a string.
• ERR:NONREAL ANSWERS is thrown when the input is a complex number and your calculator is in REAL mode.
• ERR:SYNTAX is thrown when trying to evaluate a command that doesn't return a value.
