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
 6        7        8
