# Math.Abs Method (Int64)

.NET Framework 4.5

Returns the absolute value of a 64-bit signed integer.

Namespace:  System
Assembly:  mscorlib (in mscorlib.dll)
```'Declaration
Public Shared Function Abs ( _
value As Long _
) As Long
```

#### Parameters

value
Type: System.Int64

A number that is greater than Int64.MinValue, but less than or equal to Int64.MaxValue.

#### Return Value

Type: System.Int64
A 64-bit signed integer, x, such that 0 x Int64.MaxValue.
ExceptionCondition
OverflowException

value equals Int64.MinValue.

The absolute value of an Int64 is its numeric value without its sign. For example, the absolute value of both 123 and -123 is 123.

The following example uses the Abs(Int64) method to get the absolute value of a number of Int64 values.

```Module Example
Public Sub Main()
Dim values() As Long = { Int64.MaxValue, 109013, 0, -6871982, Int64.MinValue }
For Each value As Long In values
Try
Console.WriteLine("Abs({0}) = {1}", value, Math.Abs(value))
Catch e As OverflowException
Console.WriteLine("Unable to calculate the absolute value of {0}.", _
value)
End Try
Next
End Sub
End Module
' The example displays the following output:
'       Abs(9223372036854775807) = 9223372036854775807
'       Abs(109013) = 109013
'       Abs(0) = 0
'       Abs(-6871982) = 6871982
'       Unable to calculate the absolute value of -9223372036854775808.
