The following shows an example of using 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 running the above example output is:
math.ceil(-45.17) : -45 math.ceil(100.12) : 101 math.ceil(100.72) : 101 math.ceil(math.pi) : 4
