PHP ROUND vs Javascript ROUND

Question

I found a very strange issue, the issue is the ROUND method in PHP and Javascript the calculation results are not the same!?

See the following example:

PHP

Answer 1

console.log(Math.round(175.5)); // 176
console.log(Math.round(-175.5)); // -175 <-why not -176!!??

175.5 its round value 176 it's value increasing.

-175.5 round value is -175. Because when I round -175.5 then it also increasing that means -175>-176.
