Math.Abs Method (Single)
Microsoft Silverlight will reach end of support after October 2021. Learn more.
Updated: September 2010
Returns the absolute value of a single-precision floating-point number.
Namespace: System
Assembly: mscorlib (in mscorlib.dll)
Syntax
'Declaration
<SecuritySafeCriticalAttribute> _
Public Shared Function Abs ( _
value As Single _
) As Single
[SecuritySafeCriticalAttribute]
public static float Abs(
float value
)
Parameters
- value
Type: System.Single
A number that is greater than or equal to Single.MinValue, but less than or equal to Single.MaxValue.
Return Value
Type: System.Single
A single-precision floating-point number, x, such that 0 ≤ x ≤Single.MaxValue.
Remarks
The absolute value of a Single is its numeric value without its sign. For example, the absolute value of both 1.2e-03 and -1.2e03 is 1.2e03.
If value is equal to NegativeInfinity or PositiveInfinity, the return value is PositiveInfinity. If value is equal to NaN, the return value is NaN.
Examples
The following example uses the Math.Abs(Single) method to get the absolute value of several Single values.
Dim values() As Single = {Single.MaxValue, 0.000000000016354, 15.098123, 0, _
-19.069713, -1.5058E+18, Single.MinValue}
For Each value As Single In values
outputBlock.Text += String.Format("Abs({0}) = {1}", value, Math.Abs(value)) & vbCrLf

' The example displays the following output:
' Abs(3.402823E+38) = 3.402823E+38
' Abs(1.6354E-11) = 1.6354E-11
' Abs(15.09812) = 15.09812
' Abs(0) = 0
' Abs(-19.06971) = 19.06971
' Abs(-1.5058E+18) = 1.5058E+18
' Abs(-3.402823E+38) = 3.402823E+38
float[] values = { Single.MaxValue, 16.354e-12F, 15.098123F, 0F,
-19.069713F, -15.058e17F, Single.MinValue };
foreach (float value in values)
outputBlock.Text += String.Format("Abs({0}) = {1}", value, Math.Abs(value)) + "\n";
// The example displays the following output:
