Abs
Calculates the absolute value of a number
Syntax
`
Declare Function Abs Overload ( ByVal number As Long ) As Long
Declare Function Abs ( ByVal number As Ulong ) As Ulong
Declare Function Abs ( ByVal number As LongInt ) As LongInt
Declare Function Abs ( ByVal number As ULongInt ) As ULongInt
Declare Function Abs ( ByVal number As Double ) As Double
`
Usage
`
result = Abs( number )
`
Parameters
`number`
Value to find the absolute value of.
Return Value
The absolute value of `number`.
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 `Abs(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 to `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 )
Print Abs( n )
n = -69
Print Abs( n )
`
Output:

    1
    3.1415
    42
    0
    69
