ABS - mkilgore/QB64pe GitHub Wiki

The ABS function returns the unsigned numerical value of a variable or literal value.

positive = ABS(numericalValue)

• ABS always returns positive numerical values. The value can be any numerical type.
• Often used to keep a value positive when necessary in a program.
• Use SGN to determine a value's sign when necessary.
• QB64 allows programs to return only positive _UNSIGNED variable values using a DIM or _DEFINE statement.

Example: Finding the absolute value of positive and negative numerical values.

 '' ''
a = -6
b = -7
c = 8
IF...THEN a < 0 THEN a = ABS(a)
b = ABS(b)
c = ABS(c)
PRINT a, b, c '' ''

 6        7        8
