Parameters

d

A double . [Edit]

Returns

A double containing the value of the largest integer less than or equal to d. If d is equal to double.NaN, double.NegativeInfinity, or double.PositiveInfinity, that value is returned.. [Edit]

Remarks

The behavior of this method follows IEEE Standard 754, section 4. [Edit]

Example

The following example demonstrates using the Math.Floor(double) method.

C# Example

using System; public class MathFloorExample { public static void Main() { Double d1 = Math.Floor(3.4); Double d2 = Math.Floor(-3.4); Console.WriteLine("Math.Floor(3.4) returns {0}", d1); Console.WriteLine("Math.Floor(-3.4) returns {0}", d2); } }

The output is

Math.Floor(3.4) returns 3
Math.Floor(-3.4) returns -4
