python中的数学函数(2)
3. fabs(): - 此函数返回数字的绝对值。
4. factorial(): - 此函数返回数字的阶乘。如果数字不是整数,则会显示错误消息
# Python code to demonstrate the working of
# fabs() and factorial()
# importing "math" for mathematical operations
import math
a = -10
b= 5
# returning the absolute value.
print ("The absolute value of -10 is : ", end="")
print (math.fabs(a))
# returning the factorial of 5
print ("The factorial of 5 is : ", end="")
print (math.factorial(b))
