ABSV makes the numeric value of a variable positive. .

Command

Syntax: ABSV X(variable)

This makes the numeric value contained in X positive, i.e. gives it its absolute value. To be precise, if X is less than 0, X is set to the negative of X (e.g. -5 is changed to 5), otherwise, it is left unchanged.

Mathematically, this is normally written as |x|. It's equivalent to the 'abs' function in various other languages.

Example

This code sets va00 to -4, and then uses ABSV on it, changing it to 4.

SETV VA00 -4
ABSV VA00
