将整数分成两个（几乎）相等的部分

本文介绍了将整数分成两个（几乎）相等的部分的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我需要将一个整数分成两个数字。有点像除以2但我只想要整数组件，例如：

I need to separate an integer into two numbers. Something like dividing by two but I only want integer components as a result, such as:

6 = 3 and 3 7 = 4 and 3

我尝试了以下内容，但我不确定它是最佳解决方案。

I tried the following, but I'm not sure its the best solution.

var number = 7; var part1 = 0; var part2 = 0; if((number % 2) == 0) { part1 = number / 2; part2 = number / 2; } else { part1 = parseInt((number / 2) + 1); part2 = parseInt(number / 2); }

这就是我想要的，但我认为这段代码不干净。

This does what I want, but I don't think this code is clean.

有更好的方法吗？

推荐答案

找到第一部分并从原始数字中减去它。

Just find the first part and subtract it from the original number.

var x = 7; var p1 = Math.floor(x / 2); var p2 = x - p1; console.log(p1, p2);

如果 x 为奇数， p1 将收到两个加数中较小的一个。您可以通过调用 Math.ceil 来切换它。

In the case of x being odd, p1 will receive the smaller of the two addends. You can switch this around by calling Math.ceil instead.
