你没有看错,整数的地板除//永远是整数,即使除不尽。要做精确的除法,使用/就可以。 因为//除法只取结果的整数部分,所以Python还提供一个余数运算,可以得到两个整数相除的余数: >>> 10 % 3 1 无论整数做//除法还是取余数,结果永远是整数,所以,整数运算结果永远是精确的。
In Python, the floor division operator is double slash (//) which is also known as integer division. The floor division operator divides the first operand by the second and rounds the result down to the nearest integer. Example Let suppose there are two numbers 10 and 3. Their floor divisi...
This example shows a basic Number class implementing floor division. The method handles division by another Number or by a regular number, returning a new Number instance with the result. The NotImplemented return value tells Python to try other methods like __rfloordiv__ if the operation isn...
(一)Floor division 和求余(modulus) //运算符先进行除法,之后将结果保留到整数; /运算符是保留小数的,生成一个float类型的数; %求余运算符,将两个数相除,返回它们的余数; (二)布尔表达式(boolean expressions) 布尔表达式的结果是true或者false; ==是关系运算符之一; 其他关系运算符:!=,>,<,>=,<=; (...
The following example overrides both division operators of a custom class Number. class Number: def __init__(self, x): self.x = x def __floordiv__(self, other): return self.x // other.x def __truediv__(self, other): return self.x / other.x my = Number(42) your = Number(...

The floor division operator handles floating-point numbers as well, although the philosophy and the working does not change at all. Let us take an example code to make it clearer for the readers to understand. The following code uses the // operator to implement floor division on floating-poi...
