Returns the remainder resulting from the division of a specified number by another specified number.
Assembly: mscorlib (in mscorlib.dll)
Return ValueType: System.Double
A number equal to x - (y Q), where Q is the quotient of x / y rounded to the nearest integer (if x / y falls halfway between two integers, the even integer is returned).
If x - (y Q) is zero, the value +0 is returned if x is positive, or -0 if x is negative.
If y = 0, NaN is returned.
This operation complies with the remainder operation defined in Section 5.1 of ANSI/IEEE Std 754-1985; IEEE Standard for Binary Floating-Point Arithmetic; Institute of Electrical and Electronics Engineers, Inc; 1985.
The method is not the same as the modulus operator. Although both return the remainder after division, the formulas they use are different. The formula for the method is:
IEEERemainder = dividend - (divisor * Math.Round(dividend / divisor))
In contrast, the formula for the modulus operator is:
Modulus = (Math.Abs(dividend) - (Math.Abs(divisor) * (Math.Floor(Math.Abs(dividend) / Math.Abs(divisor))))) * Math.Sign(dividend)
