python的取整函数：向上取整，向下取整，四舍五入取整

#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) #四舍五入 print "\nround---" print "round(2.3) => ", round(2.3) print "round(2.6) => ", round(2.6) #这三个的返回结果都是浮点型 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)
