Typ: Numeric Function General Programming-Syntax: ABS(<numeric-expression>)
ABS evaluates to the absolute value (value without the sign) of the given numeric term.
If the term has no numeric value, the BASIC error ?TYPE MISMATCH ERROR [IN line] occurs. It can only be used for values from -1e+38 to 1e+38. If the argument is out of range the BASIC error?OVERFLOW ERROR [IN line] is shown.
When the numeric argument is absent, it displays a ?SYNTAX ERROR [IN line].
