这个操作符由两个向右的斜线(forward slash)组成,对应英文是 “floor division”。 2.英文解释: If you imagine a room where 3 is on the ceiling and 2 is on the floor. 2.5 would fit in the middle. Floor division means the "//" will always take the floor or the lower number.[2] 假想一...
Python当中int 和 floor/ceil 的区别 floor() rounds down. int() truncates. The difference is clear when you use negative numbers:>>> import math >>> math.floor(-3.5) -4 >>> int(-3.5) -3 Rounding down on negative numbers means that they move away from 0, truncating moves them ...
What this means is that if we take the equation - 14 // 4, then it returns -3.5, which rounds off to -4 instead of -3 on flooring. The following code uses the // operator to implement floor division on negative numbers in Python. 1 2 3 4 x = - 14 // 4 print(x) The abo...

The // operator in Python 3 is used to perform floor-based division. This means that a // b first divides a by b and gets the integer quotient, while discarding the remainder. This means that the result of a//b is always an integer. Python // Operator Examples Here are a few examp...
