What is Math.Floor() in C#?
C# has a built-in Math class that provides useful mathematical functions and operations. The class has the Floor() function, which is used to compute the largest integral value less than or equal to a specified number.
Decimal variant
Syntax
public static decimal Floor (decimal value);
Parameters
value:valueis of theDecimaltype and represents the input value, which is determined by findingFloor(). Its range is all decimal numbers.
Return value
Decimal:Floor()returns the largestDecimalnumber less than or equal tovalue.
Double variant
Syntax
public static double Floor (double value);
Parameters
value:valueis of theDoubletype and represents the input value for which we have to findFloor(). Its range is all double numbers.
Return value
Double:Floor()returns the largestDoublenumber less than or equal tovalue.- If
valueis NaN, infinity, or negative infinity, that value is returned.
Example
using System;class Educative{static void Main(){decimal input = 22.32m;decimal result = Math.Floor(input);System.Console.WriteLine("Floor Decimal (22.32) = "+ result);decimal input1 = 22.0m;decimal result1 = Math.Floor(input1);System.Console.WriteLine("Ceiling Decimal (22.0) = "+ result1);double input2 = 22.32;double result2 = Math.Floor(input2);System.Console.WriteLine("Floor Double (22.32) = "+ result2);double input3 = 22.00;double result3 = Math.Floor(input3);System.Console.WriteLine("Floor Double (22.00) = "+ result3);}}
