Python exp () function
description
exp () method returns the index of x, e x.
grammar
The following is the syntax exp () method:
import math math.exp( x )
Note: exp () is not directly accessible, we need to import math module, invoke the method through static object.
parameter
- x - numeric expression.
return value
Return the exponent of x, e x.Examples
The following illustrates the use of exp () method Example:
#!/usr/bin/python import math # 导入 math 模块 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)
After running the above example output is:
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
