I want to fixed it as 12.14. How can we set two digits after decimal in PHP?

Have you tried `number_format` or any functions? – chris85 Jul 02 '17 at 17:54 — chris85, Jul 02 '17 at 17:54

7

In your example :

var $b = 7;

var $c = $a/$b;

echo round($c, 2);

Hope it helps

It should probably be `floor()` and not round(). Round will make 87.555 -> 87.56, Floor() makes it 87.55 as requested in the question. But who knows, it may be a typo from OP. – Andreas Jul 02 '17 at 18:06
Yes my bad. Anyway there is some function and PHP Documentation is full of it with examples :p – Laurent Plantrose Jul 02 '17 at 18:17
