Gets the absolute value (or magnitude) of a complex number.
Assembly: System.Numerics (in System.Numerics.dll)
The absolute value of a complex number is equivalent to its Magnitude property. The absolute value of a real number a + bi is calculated as follows:
If b = 0, the result is 0.
If a > b, the result is a * Math.Sqrt(1 + b2/a2).
If b > a, the result is b * Math.Sqrt(1 + a2/b2).
If the calculation of the absolute value results in an overflow, the method returns either Double.PositiveInfinity or Double.NegativeInfinity. If either the Real or Imaginary property is Double.NaN and the other property is neither Double.PositiveInfinity nor Double.NegativeInfinity, the method returns Double.NaN.
