The [[ABS]] function returns the unsigned numerical value of a variable or literal value.
|
|
|
|
|
|
{{PageSyntax}}
|
|
:{{Parameter|positive}} = [[ABS]]({{Parameter|numericalValue}})
|
|
|
|
|
|
{{PageDescription}}
|
|
* [[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.
