MathF.Abs(Single)方法用于返回指定浮点数的绝对值。
Syntax: public static float Abs (float x);
Here, it takes a standard floating point number.
Return Value: This method returns a floating point value less than Single.MaxValue.
范例1：
// C# program to demonstrate the
// MathF.Abs(Single) Method
using System;
class GFG {
// Main Method
public static void Main()
{
// Declaring and initializing value
float value = 4.5f;
// Getting absolute float
// using Abs() method
float round = MathF.Abs(value);
// Display the value
Console.WriteLine("Absolute float value is {0}",
round);
}
}
输出：
Absolute float value is 4.5
范例2：
// C# program to demonstrate the
// MathF.Abs(Single) Method
using System;
using System.Globalization;
class GFG {
// Main Method
public static void Main()
{
// calling get() method
get(20f);
get(30.5f);
get(40.5f);
get(4294.586f);
}
// defining get() method
public static void get(float value)
{
// getting absolute float
// using Abs() method
float round = MathF.Abs(value);
// Display the value
Console.WriteLine("Float value is {0}", round);
}
}
输出：
Float value is 20
Float value is 30.5
Float value is 40.5
Float value is 4294.586
