PHP - number_format question

  • March 6, 2010

I want to format a number without rounding it.  For example, I have a number that is 5.77890 and I just want to drop the 7890 and display 5.7, but without rounding it up.  Right now I am using number_format but it's rounding it to 5.8.  How can this be done?

David,

I copied this code, into a blank document and still got a T_Variable error?


I don't see how you can get an error by running that code. Here is a screenshot of it running in Live View. You can see the output "3.3" in Design view.

I have also attached the original PHP code.

If you don't want the number to be rounded up, you will need to use string manipulation functions to achieve what you want. The following custom function will do it for you:

function stripNum($num, $decplaces = 1) {
  $pos = strpos($num, '.');
  return substr($num, 0, $pos+1+$decplaces);
}

This finds the decimal point, and returns the value truncated to the number of decimal places specified by the second (optional) argument.

$original = 5.77890;
echo stripNum($original);   // displays 5.7
echo stripNum($original, 2) // displays 5.77

If there's no decimal point, you just get the original number.

David, I tried this below and am getting a T_Variable error on the line $pos

= strops($num, '.'); HERE is my code:

<?php function stripNum($num, $decplaces = 1) {

  $pos = strpos($num, '.');

  return substr($num, 0, $pos1$decplaces); }

if ($row_getCountin12['countin12'] >= 20) {

if (((($row_getHandi['sum_hand']) - ($row_getTourd['handi'])) < 3))

{

echo stripNum($row_getHandi['sum_hand']);

}

} ?>

Thanks.

You have got this:

$pos1$decplaces

It should be:

$pos+1+$decplaces

Or if you prefer to spread things out:

$pos + 1 + $decplaces
