PHP dropping decimals without rounding up

You need floor() in this way:

$rounded = floor($float*100)/100;

Or you cast to integer:

$rounded = 0.01 * (int)($float*100);

This way it will not be rounding up.

$float = 1.505;

echo sprintf("%.2f", $float);

//outputs 1.50

Use the PHP native function bcdiv

echo bcdiv(2.56789, 1, 2);  // 2.56
