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

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.

Answer 2

Use the PHP native function bcdiv

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

Answer 3

$float = 1.505;

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

//outputs 1.50
