Decimal.Round Method (Decimal)

Rounds a decimal value to the nearest integer.

Namespace:  System
Assembly:  mscorlib (in mscorlib.dll)

public static decimal Round(
	decimal d
)

Parameters

d
Type: System.Decimal

A decimal number to round.

Return Value

Type: System.Decimal
The integer that is nearest to the d parameter. If d is halfway between two integers, one of which is even and the other odd, the even number is returned.

ExceptionCondition

The result is outside the range of a Decimal object.

The behavior of this method follows IEEE Standard 754, section 4. This kind of rounding is sometimes called rounding to nearest or banker's rounding. It minimizes rounding errors that result from consistently rounding a midpoint value in a single direction. It is equivalent to calling the Round(Decimal, MidpointRounding) method with a mode argument of MidpointRounding.ToEven.
