0、In Python 2, the / operator usually meant integer division, but you could make it behave like floating point division by including a special directive in your code. In Python 3, the / operator always means floating point division.
# 除法(整数除法,结果向下取整) division_result = 7 // 2 # 结果为 3 # 取模(求余数) modulus_result = 9 % 4 # 结果为 1 # 幂运算 power_result = 2 ** 3 # 结果为 8 2.浮点型(Floating Point Numbers) 语法: 浮点型数据包含小数部分,用于表示实数。在 Python 中,你可以通过直接赋值一个小...
5.0 >>> 8 / 5 # division always returns a floating point number除法总是返回浮点数（当然在正式中您可以限制小数点后的位数）1.6 The integer numbers (e.g. 2, 4, 20) have type int, the ones with a fractional part (e.g. 5.0, 1.6) have type float. We will see more about num...
说1 ]=> +inf生成这些值也不容易:看起来应该计算到浮点无穷大的表达式根本不容易;Floating-point division by zero 如何在MIT方案 浏览4提问于2015-04-13得票数1 回答已采纳 2回答 在Python2.7中将无穷大表示为整数 、、 我想知道如何在Python2.7中将inf和-inf定义为int。我试过了,inf和-inf似乎只能作为float...

isfloating point division, and the latter is floor division, sometimes also called integer division....
A zero division error is caused if the right argument is zero. These arguments can be floating-point numbers. We find that the absolute value for the result is smaller than the second operand. And the result of using the modulo operator will always yield the same sign as the second operand...
>>> from __future__ import division >>> 5 / 2 2.5 >>> 9 / 2 4.5 >>> 9.0 / 2 4.5 >>> 9 / 2.0 4.5 1. 2. 3. 4. 注意了,引用了一个模块之后,再做除法,就不管什么情况,都是得到浮点数的结果了。 这就是轮子的力量。 余数 ...
(with rounding of fractions downwards) when you type 1/3 and “floating-point” (or decimal) division when you type 1.0/3.0. In order to get the expected behavior of division (standard in Python 3.0), you need to type: from __future__import division. Python中/是整除,要用真正的除法...
The Python ZeroDivisionError: float division by zero occurs when we try to divide a floating-point number by `0`.
