C# has a built-in Math class that provides useful mathematical functions and operations. The class has the Ceiling() function, which is used to compute the smallest integral value greater than or equal to a specified number.
public static decimal Ceiling (decimal value);
value: value is of the Decimal type and represents the input value, which is determined by finding Ceiling(). Its range is all decimal numbers.Decimal: Ceiling() returns the smallest Decimal number greater than or equal to value.public static double Ceiling (double value);
value: value is of the Double type and represents the input value for which we have to find Ceiling(). Its range is all double numbers.Double: Ceiling() returns the smallest Double number greater than or equal to value.value is NaN, infinity, or negative infinity, that value is returned.using System;class Educative{static void Main(){decimal input = 22.32m;decimal result = Math.Ceiling(input);System.Console.WriteLine("Ceiling Decimal (22.32) = "+ result);decimal input1 = 22.0m;decimal result1 = Math.Ceiling(input1);System.Console.WriteLine("Ceiling Decimal (22.0) = "+ result1);double input2 = 22.32;double result2 = Math.Ceiling(input2);System.Console.WriteLine("Ceiling Double (22.32) = "+ result2);double input3 = 22.00;double result3 = Math.Ceiling(input3);System.Console.WriteLine("Ceiling Double (22.00) = "+ result3);}}
