对 PHP 中的数字进行完美舍入

Question

So, i retrieved with an API a number, which is 1441971834999104426 . I would like to round it to 1441971835

However, when i do: round(1441971834999104426, -9); the output is: 1.441971835E+18 , which is not what i want at all.

Can you give me some advices on how I can do the rounding perfectly?

Thanks to you.

Answer 1

Divide the number by 1e9 , and round that.

echo round(1441971834999104426/1e9);
