#encoding:utf-8
import math

#向上取整
print "math.ceil---"
print "math.ceil(2.3) => ", math.ceil(2.3)
print "math.ceil(2.6) => ", math.ceil(2.6)

#向下取整
print "\nmath.floor---"
print "math.floor(2.3) => ", math.floor(2.3)
print "math.floor(2.6) => ", math.floor(2.6)

#四捨五入
print "\nround---"
print "round(2.3) => ", round(2.3)
print "round(2.6) => ", round(2.6)

#這三個的返回結果都是浮點型
print "\n\nNOTE:every result is type of float"
print "math.ceil(2) => ", math.ceil(2)
print "math.floor(2) => ", math.floor(2)
print "round(2) => ", round(2)

 

返回如下：
