multiplication math not working ?

One
hi group -

I had this in a function - so I've just moved this out of the function
for readabilty.

Can someone please tell me WHY does this not return the result of :
n1 times n2

As I said - I took it out of the function just for readability :
In my php file :

$number_percent ="25";
echo "history['order_total'] is ".$history['order_total']."<br />";
echo "number_per cent is ".$number_perce nt."<br />";
$total=(($histo ry['order_total'])*$number_perce nt);
echo "total is ".$total."< br />";

And here is the output in the browser :
history['order_total'] is $241.47
number_percent is 25
total is 0

WHY ? Any advice or pointers would be much appreciated!

There must be something else going on with your currency string.
Please use this on that string, and report it's results back to us:

echo preg_replace('/(.)/se','"[".ord("$1") ."]"',$history['order_total']);

Thanks again Rik - here you go :

Input :
echo "history['order_total'] is ".$history['order_total']."<br />";
echo preg_replace('/(.)/se','"[".ord("$1") ."]"',
$history['order_total']);
exit;

Output :
history['order_total'] is $241.47

$history['order_total'] contains '<b>$241.47</b>'. This is not a number.

$history['order_total'] = (float)preg_rep lace('/[^0-9\.]/', '',
strip_tags($his tory['order_total']));

Javascript has a very small math function list. However there is no reason that this list can not be extended greatly.

In that case you need much more ram than a PC has to store functions calculated in loops so that you do not have to recalculate every time you cycle through the nest of loops. Using a HD for storage to extend ram is much too slow for many...
