PHP How to round decimal numbers up?

Question

I would like to round my decimal number.

As I search on tutorial, We can use round function.

Example I have this number 7.1 , when I tried to round it using

echo round("7.1");

It will show us: 7

But now I want if 7.1 it should be 8 . Is it possible to do it?

Answer 1

我建议使用ceil函数，该函数会将数字四舍五入到最接近的值。

echo ceil('7.1');

Answer 2

There is 3 rounding functions: ceil , floor , round .

Ceil will round numbers up. documentation

Floor will round numbers down. documentation

Round will round following basic rounding rules. 0.5 and higher rounds up. 0.4 and lower rounds down. documentation
