Examples

The following example demonstrates the use of the ceil() method:

#!/usr/bin/python3
import math   # 导入 math 模块

print ("math.ceil(-45.17) : ", math.ceil(-45.17))
print ("math.ceil(100.12) : ", math.ceil(100.12))
print ("math.ceil(100.72) : ", math.ceil(100.72))
print ("math.ceil(math.pi) : ", math.ceil(math.pi))

After the above example runs, the output is:

math.ceil(-45.17) :  -45
math.ceil(100.12) :  101
math.ceil(100.72) :  101
math.ceil(math.pi) :  4
