 exp()方法返回指数x： ex.
语法

以下是exp()方法的语法：

import math

math.exp( x )
Copy after login

注意：此函数是无法直接访问的，所以我们需要导入math模块，然后需要用math的静态对象来调用这个函数。
参数

  • x -- 这是一个数值表达式

返回值

此方法返回指数x： ex.
例子

下面的例子显示了exp()方法的使用。

#!/usr/bin/python
import math  # This will import math module

print "math.exp(-45.17) : ", math.exp(-45.17)
print "math.exp(100.12) : ", math.exp(100.12)
print "math.exp(100.72) : ", math.exp(100.72)
print "math.exp(119L) : ", math.exp(119L)
print "math.exp(math.pi) : ", math.exp(math.pi)
Copy after login

当我们运行上面的程序，它会产生以下结果：

math.exp(-45.17) : 2.41500621326e-20
math.exp(100.12) : 3.03084361407e+43
math.exp(100.72) : 5.52255713025e+43
math.exp(119L) : 4.7978133273e+51
math.exp(math.pi) : 23.1406926328
Copy after login
