{{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 values sign when necessary.
|
||
|
* '''QB64''' allows programs to return only positive [[_UNSIGNED]] variable values using a [[DIM]] or {{KW|_DEFINE}} statement.
