The ABS function returns the unsigned numerical value of a variable or literal value.
Syntax
- positive = ABS(numericalValue)
Description
- 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.
Examples
Example: Finding the absolute value of positive and negative numerical values.
a = -6 b = -7 c = 8 IF a < 0 THEN a = ABS(a) b = ABS(b) c = ABS(c) PRINT a, b, c |
