Math.Abs Method (Single)
Returns the absolute value of a single-precision floating-point number.
Assembly: mscorlib (in mscorlib.dll)
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.SingleA single-precision floating-point number, x, such that 0 ≤ x ≤ Single.MaxValue.
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.
The following example uses the Abs(Single) method to get the absolute value of a number of Single values.
float[] values= { Single.MaxValue, 16.354e-12F, 15.098123F, 0F, -19.069713F, -15.058e17F, Single.MinValue }; foreach (float value in values) Console.WriteLine("Abs({0}) = {1}", value, Math.Abs(value)); // 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
