方法二:import未来支持的语言特征division(精确除法) Python的'/'除法默认使用截断除(Truncating Division),导入division模块后,Python才会默认使用精确除法。当导入了精确除后,若想再使用截断除,可以使用取整除'//',同时也被成为地板除。 In [92]: %%file testFloat.py from __future__ import division a = 1 ...
bit operators. Arithmetic operators, python arithmetic operators add exponents (**) and divisor (//) on the basis of addition (+) minus (-) multiplied by (*) divided by (/) remainder (%). Add, subtract, multiply and divide without further ado. The remainder is the remaining value after...
% Binary Modulo a % b The remainder of a divided by b // Binary Floor division or integer division a // b The quotient of a divided by b, rounded to the next smallest whole number ** Binary Exponentiation a**b a raised to the power of b Note that a and b in the Sample Express...
import operator operator.mod(3 , 4) #输出 3 operator.mod(10 , 2) #输出 0 operator.mod(6 , 4) #输出 2 当然, 你也可以用负数 : -9 % 7 #输出 5 9 % -7 #输出 -5 -9 % -7 #输出 -2 如果需要找到整数除法和模数的结果,可以使用divmod函数: quotient, remainder = divmod(9, 4) ...

The built-in function divmod() is also an example of a function that returns multiple values. The function takes two (non-complex) numbers as arguments and returns two numbers, the quotient of the two input values and the remainder of the division:...

>>> 17 % 3 # the % operator returns the remainder of the division 2 >>> 5 * 3 + 2 # result * divisor + remainder 17 With Python, it is possible to use the ** operator to calculate powers: >>> 5 ** 2 # 5 squared
Division (/) always returns a float. To do floor division and get an integer result (discarding any fractional result) you can use the // operator; to calculate the remainder you can use %:除法总是返回一个浮点数值，若要获得整数结果（丢弃任何小数结果），可以使用//运算符；除法计算余数可以...
