If you know TI-83 BASIC, please write code for some of the tasks not implemented in TI-83 BASIC.

TI-83 BASIC is not affiliated with BASIC .

TI-83 BASIC or TI-BASIC 83 is the high-level language used on TI-83/84/83+/84+ Z80 calculators (aside from the assembly which is also on the calculator).

Elements of language[edit]

Control flow[edit]

The language contains control flow for structured programming. The main control flow statements are:


If condition




While condition


Repeat condition

Data types[edit]

TI-BASIC is a strongly and dynamically-typed language Variables are global. There is no local variables. So programs cannot be recursive, even if a program can call itself.

  • Numerical variables, 27 variables from A to Z and theta. These allow real numbers or complex numbers (implemented as pairs of reals) to be stored in floating point format. Values may range from 1E-99 to 1E99 with up to ten digits of accuracy.
  • Strings, 10 strings from Str1 to Str9 and Str0.
  • Lists, including L1 - L6, with the ability to create additional ones. These are essentially one-dimensional arrays used to store a real or complex number into each of their elements. (L1(4) would return the value of L1 at n=4)
  • Matrices, 8 matrices from [A] to [J]. Their elements are subject to the same restrictions as lists. Their dimensions may be defined up to 99x99 elements, although, again, available memory will limit this. ([A](3,4) would design item at row=3 column=4)
  • Equation variables, 10 y(x) functions: from Y1 to Y9 and Y0, 6 r(theta) polar functions: r1 - r6, and 3 u(n) integer sequences: u, v, w. (Y1(4) would return the value of Y1 at X=4, X is a real)


One popular example is the quadratic formula program.

Prompt A,B,C

As far there is a complex mode and variable can be real or complex, this program is very ubiquitous.
