# Double.Round Method

## Definition

 Round(Double) Rounds a value to the nearest integer using the default rounding mode (ToEven). Round(Double, Int32) Rounds a value to a specified number of fractional-digits using the default rounding mode (ToEven). Round(Double, MidpointRounding) Rounds a value to the nearest integer using the specified rounding mode. Round(Double, Int32, MidpointRounding) Rounds a value to a specified number of fractional-digits using the default rounding mode (ToEven).

## Round(Double)

Double.cs

Rounds a value to the nearest integer using the default rounding mode (ToEven).

``````public:
static double Round(double x) = System::Numerics::IFloatingPoint<double>::Round;``````
``public static double Round (double x);``
``static member Round : double -> double``
``Public Shared Function Round (x As Double) As Double``

#### Parameters

x
