Examples

The following shows an example of the use of fabs () method:

#!/usr/bin/python
# -*- coding: UTF-8 -*-

import math   # 导入数学模块

print "math.fabs(-45.17) : ", math.fabs(-45.17)
print "math.fabs(100.12) : ", math.fabs(100.12)
print "math.fabs(100.72) : ", math.fabs(100.72)
print "math.fabs(119L) : ", math.fabs(119L)
print "math.fabs(math.pi) : ", math.fabs(math.pi)

After running the above example output is:

math.fabs(-45.17) :  45.17
math.fabs(100.12) :  100.12
math.fabs(100.72) :  100.72
math.fabs(119L) :  119.0
math.fabs(math.pi) :  3.14159265359
