在C＃中， MathF.Ceiling(Single)是MathF类方法。此方法用于查找最小整数，该整数大于或等于参数列表中指定的单值或浮点值。
Syntax: public static float Ceiling (float x);
Here, x is the float(Single) value whose ceiling value has to be calculated.
返回类型：此方法返回最小的整数值，该值将大于或等于x 。
例子：
// 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);
}
}
输出：
Input Value = 33
Ceiling value = 33
Input Value = 99.99
Ceiling value = 100
