The [ABS](ABS) function returns the unsigned numerical value of a variable or literal value.
|
|
|
|
## Syntax
|
|
|
|
> positive = [ABS](ABS)(numericalValue)
|
|
|
|
## Description
|
|
|
|
* [ABS](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](SGN) to determine a value's sign when necessary.
|
|
* **QB64** allows programs to return only positive [_UNSIGNED](_UNSIGNED) variable values using a [DIM](DIM) or [_DEFINE](_DEFINE) statement.
|
|
|
|
## Example(s)
|
|
|
|
Finding the absolute value of positive and negative numerical values.
|
|
|
|
```vb
|
|
|
|
a = -6
|
|
b = -7
|
|
c = 8
|
|
IF a < 0 THEN a = ABS(a)
|
|
b = ABS(b)
|
|
c = ABS(c)
|
|
PRINT a, b, c
|
|
|
|
```
