PHP dropping decimals without rounding up

Question

I want to drop off decimals without rounding up. For example if I have 1.505, I want to drop last decimal and value should be 1.50. Is there such a function in PHP?

Answer 1

Its easy and work better.

$value = 12.9987876;
$value_exp = explode(".", $value);
$value_new = floatval($value_exp[0].'.'.substr($value_exp[1],0,4));

echo $value_new; // output will 12.9987
