TI-83 BASIC
This programming language may be used to instruct a computer to perform a task.

Lang tag(s):	ti83b
See Also:	TI-83 BASIC on the HOPL

Listed below are all of the tasks on Rosetta Code which have been solved using 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[edit]

<lang ti83b>If condition Then ... Else ... End</lang>

For[edit]

<lang ti83b>For(variable,start,stop,step) ... End</lang>

While[edit]

<lang ti83b>While condition ... End</lang>

Repeat[edit]

<lang ti83b>Repeat condition ... End</lang>

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)

Example[edit]

One popular example is the quadratic formula program. <lang ti83b>Prompt A,B,C B²-4AC->D (-B-sqrt(D))/(2A)->Y (-B+sqrt(D))/(2A)->X {Y,X}</lang> As far there is a complex mode and variable can be real or complex, this program is very ubiquitous.
