Oops! That should be..
<pre>
$my_float = 2.683526;
$new_number = number_format($my_float,2)
echo $new_number;
</pre>
The result would be.. 2.68

Surrogates of the comma and decimal point may not be strings. Id est:

$NUMBER = number_format(200000, 2, "CHICKEN", "JOHNNY");

print $NUMBER;

The first line will be interpreted as having two parameters: the number itself and the number of decimal spaces beyond the decimal point.

The second line will output so:

200,000.00

to turn variable $Var = '324' into 324.00 or $Var = '324.9' into 324.90 or $Var = 324.914 into 324.91, use:
<PRE>
Number_Format($Var, 2);
</PRE>

For a number in Italian LIRE style:
&lt;?
$PREZZO=1000000;
$LIRE=number_format($PREZZO,0,".",".");
echo $LIRE;
?>
output: 1.000.000

excused the repetition

The arguments in the function definition
should read:

(float number [, int decimals[, string dec_point, string thousands_sep]])

You can't have an empty thousands separator yet. This functionality is in 4.0.2, where you can just set it to "".

If you want to work around the thousands-separator-bug/feature where you can't format a number without thousand separators use str_replace("A","",number_format($number,2,".","A"))
