Round decimal number to .5 when decimal is below .5 - PHP

Question

Is there any way to round up decimal number to .5 if the decimal value is below or equal to .5 instead of rounding up to whole number?

Ex:

0.12  => 0.5
0.23  => 0.5
12.39 => 12.5...

but when the decimal value is greater than .5 round the number up

0.51   => 1.0
0.60   => 1.0
12.80  => 13.0

If x is your variable do Ceil($x * 2) / 2 Which will round your number to the nearest whole number or 0.5

Did you mean to use `ceil()`? – ArSeN May 04 '20 at 13:36
0.12 * 2 -> 0.24 - you floor that you get 0 and not 0.5. I think your solution would work with `ceil()` – ArSeN May 04 '20 at 13:38
