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
