Decimal Places

Hi,

How do ensure a data is not longer than 0.1 decimal places? thanks

Try this:

$var = 3.222222;
$var = number_format($var, 1);
echo($var);      // Prints "3.2"

That should do the trick.

Hmm
This is my code:

$average_rate = round($average_rate, 2);

Is it the same?
Its to two decimal places

It's not exactly the same. round() rounds the number off to the number of decimal places you specify, while number_format just cuts it down to the number of places you specify.

Here's an example:

$num = "3.456";
$num = round($num, 2);
echo($num);      // Prints "3.46"

/* -------------------------------- */

$num2 = "3.456";
$num2 = number_format($num2, 2);
echo($num2);      // Prints "3.45"

See the difference?
