在C#中,MathF.Sqrt(Single)是MathF類(在係統名稱空間中存在)方法,用於計算指定的Single或float數據類型值的平方根。
用法: public static float Sqrt (float x);
Here, x is the number whose square root is to be calculated and type of this parameter is System.Single.
返回類型:此方法返回x的平方根。如果x等於NaN,NegativeInfinity或PositiveInfinity,則返回該值。此方法的返回類型為System.Single。
下麵的示例說明了上述方法的使用:
示例1:
// C# program to demonstrate the
// MathF.Sqrt(Single) Method
using System;
class GFG {
// Main Method
public static void Main()
{
// taking positive value
float x = 78521F;
// taking negative value
float x1 = -7824F;
// Input positive value
// Output will be square
// root of x
Console.WriteLine(MathF.Sqrt(x));
// Input negative value,
// Output will be NaN
Console.Write(MathF.Sqrt(x1));
}
}
輸出:
280.216 NaN
示例2:
// C# program to demonstrate the MathF.Sqrt()
// method when the argument is positive
// or negative Zero
using System;
class GFG {
// Main Method
public static void Main()
{
// taking positive zero
float x = 0f;
Console.WriteLine(MathF.Sqrt(x));
// taking negative zero
float y = -0f;
Console.Write(MathF.Sqrt(y));
}
}
輸出:
0 0
