MathF.Ceiling() Method in C# with Examples

In C#, MathF.Ceiling(Single) is a MathF class method. This method is used to find the smallest integer , which is greater than or equal to the specified single or float value in the argument list.

Syntax: public static float Ceiling (float x);
Here, x is the float(Single) value whose ceiling value has to be calculated.

Return Type: This method return the smallest integral value which will be greater than or equal to x.

Example:

// C# program to illustrate the
// MathF.Ceiling(Single) Method
using System;

class GFG {

    // Main method
    static void Main()
    {

        // taking float values
        float x1 = 33.00f;
        float x2 = 99.99f;

        // Calculate Ceiling values by
        // Using MathF.Ceiling() method
        float r1 = MathF.Ceiling(x1);
        float r2 = MathF.Ceiling(x2);

        // Print the original values
        // and Ceiling values
        Console.WriteLine("Input Value  = " + x1);
        Console.WriteLine("Ceiling value = " + r1);

        // Print the original values
        // and Ceiling values
        Console.WriteLine("Input Value  = " + x2);
        Console.WriteLine("Ceiling value = " + r2);
    }
}

Output:

Input Value  = 33
Ceiling value = 33
Input Value  = 99.99
Ceiling value = 100
