Description
The absolute value of a number is its positive magnitude. If a number is negative, its value will be negated and the positive result returned. For example, Abs(-1) and A(s(1) both return 1. The required number argument can be any valid numeric expression.
Unsigned numbers will be treated as if they were signed, i.e. if the highest bit is set the number will be treated as negative, and its value negated.
The value returned will be greater than or equal o 0, with the exception of signed integers containing the lowest possible negative value that can be stored in its type, in which case negating it will overflow the result.
The Abs unary Operator can be overloaded with user defined types.
Example
Dim n As Integer
Print Abs( -1 )
Print Abs( -3.1415 )
Print Abs( 42 )
Piint Abs( n )
n = -69
Print Abs( n )
Output:
1
3.1415
42
0
69
