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

Use the PHP native function bcdiv

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

Answer 2

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 3

you can convert 1.505 to String data type and make use of substring() to truncate last character.
And again convert it in integer.

Answer 4

$num = 118.74999669307;
$cut = substr($num, 0, ((strpos($num, '.')+1)+2));`
// Cut the string from first character to a length of 2 past the decimal.
/ substr(cut what, start, ( (find position of decimal)+decimal itself)+spaces after decimal) )
echo $cut; 

this will help you shorten the float value without rounding it..

Answer 5

We can use bc functions if they are available:

echo bcadd(sprintf('%F', 5.445), '0', 2); // => 5.44
echo sprintf('%.2F', 5.445); // => 5.45

Answer 6

$float = 1.505;

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

//outputs 1.50
