请解释为什么17％40 = 17 [英] Please explain why 17 % 40 = 17

问题描述

我是Java的新手，实际上是一般的编程.我知道模数运算符(％)返回两个数字的余数，但是我不明白为什么17％40 = 17.

I am new to Java, actually programming in general. I understand that the modulus operator (%) returns the remainder of two numbers, however, I do not understand why 17 % 40 = 17.

我知道40％17 = 6，而17％5 = 2，而40％5 = 0.但是17％40 = 17让我感到难过.

I understand that 40 % 17 = 6, and 17 % 5 = 2, and 40 % 5 = 0. I get the gist of what value is returned as the remainder. But 17 % 40 = 17 has me stumped.

我可以设计的唯一合理化方法是，由于余数小于1，因此返回总值17，为什么不返回0?请帮我解释一下这个谜.

The only rationalization I can devise is that since the remainder is less than 1 the total value 17 is returned, why not 0? Please help to explain this enigma to me.

推荐答案

除以17/40时，商为0，余数为17.

When you divide 17/40, quotient is 0 and the remainder is 17.

取模运算符(%)返回余数.

即

a % b = remainder of a / b
