如何在PHP中基于小数点添加或减去金额 [英] How can I add or subtract amount based on decimal points in PHP

问题描述

如何根据PHP / CI中的小数点添加或减去金额？即如果金额为5.11则应返回5，如果金额为5.66，则应返回6.如果小数大于50则减去+1，如果小于或等于50则减去减去



我尝试了什么：



我们可以使用十进制检测然后ceil和floor函数相应但是寻找是否有库或函数avaliable

解决方案

你所描述的只是正常的舍入（除非我遗漏了什么）



PHP通过圆形功能实现这一点。



round（5.11）;

round（5.6）;

How can I add or subtract amount based on decimal points in PHP / CI? I.e. if the amount is 5.11 it should return 5 and if amount is 5.66 it should return 6. Subtract +1 if decimal is greater then 50 and subtract if lesser or equal to 50

What I have tried:

We can use decimal detection and then ceil and floor function accordingly but seeking if there is library or function avaliable

解决方案

What you've described is just normal rounding (unless I am missing something)

PHP accomplishes this with the round function.

round(5.11);
round(5.6);
