在C＃中， MathF.Floor(Single)是MathF类方法。此方法用于查找最大整数，该整数小于或等于参数列表中指定的浮点值。
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.
例子：
// 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));
}
}
输出：
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
