Editing TI-BASIC (section)

==== TI-89 (68k) ====
* Integers, which can store a large amount of data.  The 68k calculators can store very large numbers, as high as <math>10^{600}</math>, with perfect accuracy.
* Real numbers, using [[decimal floating point]].  These store up to 14 significant digits depending on the calculator model.
* [[Complex numbers]], implemented as pairs of reals.
* [[String (computer science)|Strings]]
* Lists, which are one-dimensional [[linked list]]s which support element-wise operations.  On the 68k calculators, elements can be integers, reals, complex numbers, strings or expressions.
* [[Matrix (mathematics)|Matrices]], with elements subject to the same restrictions in lists
* [[Symbolic computation|Symbolic expressions]], unique to the 68k series.

Data types that cannot be directly manipulated (typing only their name on a line would result in an error) include:
* Pictures
* Data
* Programs
* Functions
