# MathF.Floor() Method in C# with Examples

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

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

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

Example:

 `// C# program to illustrate the ` `// MathF.Floor(Single) Method ` `using` `System; ` ` `  `class` `GFG { ` ` `  `    ``// Main method ` `    ``static` `void` `Main() ` `    ``{ ` ` `  `        ``// taking float values ` `        ``float` `x1 = 37.00f; ` `        ``float` `x2 = 99.99f; ` `        ``float` `x3 = 0.2154f;  ` `        ``float` `x4 = 123.123f;  ` `        ``float` `x5 = -2.2f;  ` `        ``float` `x6 = -123.123f;  ` `         `  `        ``// calling the method ` `        ``result(x1); ` `        ``result(x2); ` `        ``result(x3); ` `        ``result(x4); ` `        ``result(x5); ` `        ``result(x6); ` `    ``} ` `     `  `     ``public` `static` `void` `result(``float` `t1) ` `     ``{ ` `        ``// Print the original values ` `        ``// and Floor values ` `        ``Console.WriteLine(``"Input Value = "` `+ t1); ` `         `  `        ``// using the MathF.Floor() Method ` `        ``Console.WriteLine(``"Floor value = "` `+ MathF.Floor(t1)); ` `     ``} ` `} `

Output:

```Input Value = 37
Floor value = 37
Input Value = 99.99
Floor value = 99
Input Value = 0.2154
Floor value = 0
Input Value = 123.123
Floor value = 123
Input Value = -2.2
Floor value = -3
Input Value = -123.123
Floor value = -124
