在C#中,Exp(Single)是MathF類方法,用於將e提升為指定的冪。這裏e是一個數學常數,其值約為2.71828。
用法: public static float Exp (float x);
Here, x is the required number of type System.Single which specifies a power.
返回類型:它返回升為System.Single類型的冪x的數字e。
注意:
- 如果x等於NaN,則返回值為NaN。
- 如果x等於PositiveInfinity,則返回值為Infinity。
- 如果x等於NegativeInfinity,則返回值為0。
示例1:
// C# Program to illustrate the
// MathF.Exp(Single) Method
using System;
class Geeks {
// Main Method
public static void Main()
{
// using the method
Console.WriteLine(MathF.Exp(7.0f));
Console.WriteLine(MathF.Exp(458.95f));
Console.WriteLine(MathF.Exp(9.487f));
Console.WriteLine(MathF.Exp(0.00f));
}
}
輸出:
1096.633 Infinity 13187.18 1
示例2:
// C# Program to illustrate the
// MathF.Exp(Single) Method by
// taking NaN, PositiveInfinity
// and NegativeInfinity]
using System;
class Geeks {
// Main Method
public static void Main()
{
// Taking NaN
Console.WriteLine(MathF.Exp(Single.NaN));
// Taking PositiveInfinity
Console.WriteLine(MathF.Exp(Single.PositiveInfinity));
// Taking NegativeInfinity
Console.WriteLine(MathF.Exp(Single.NegativeInfinity));
}
}
輸出:
NaN Infinity 0
