[PHP] Modulus and floating point...
Consider the following: $number = 102.52; echo $number % 50; echo bcmod( $number, 50 ); in both cases, it's spitting out 2. Why is it not spitting out 2.52? Is there a way I can get that information? w/o having to parse the string, breaking it up, getting the modulus and then adding it back into the end result...? Chris
Re: [PHP] Modulus and floating point...
You can consider doing this: $number=102.52; $fraction=$number-floor($number); $number=($number % 50)+$fraction; Basically it's the exact solution you're suggesting, just that you don't have to do any string stuff. PHP's behaviour is normal - modulus is generally intended for integers...

Re: [PHP] Modulus Formatting
Hi Michael,
Use a temporary variable [counter], if counter%3 == 0 then
write /trtr in the output.
$counter=0; print "tr";
while($row = mysql_fetch_array($result)) {
echo "td".$row["user_id"]."/td"; $counter++;
if (!$counter%3) { echo "/trtr"; }
}
That's all ;-)

Subject: [PHP] Modulus Formatting
I can pull data out of a database using mysql_fetch_array and assemble
it like this using a while statement:
TRTD$data/TD/TR
TRTD$data/TD/TR
TRTD$data/TD/TR
etc ...
What I'd like to do is assemble it like this:
TRTD$data/TDTD$data/TDTD$data/TD/TR
etc...
In other words, I need a break (/TRTR) every three times through the
loop.
I've tried several snippets of code from this list's archive but none seem
to work. I've tried while statements, for statements and the list function
in every combination I can think of ... no go. I know that modulus is
what I need but I can't crack the right code combination.
Does anyone have a solution or can they point me to a resource somewhere?
Thanks
Mick

4%2 = 0 4 div 2 equals remainder 0 2 div 4 doesnt divide so your left with the remainder equal to what you started with, 2 -- Chris Lee Mediawaveonline.com [EMAIL PROTECTED] ""Mike P"" [EMAIL PROTECTED] wrote in message 94qjq0$rde$[EMAIL PROTECTED]">news:94qjq0$rde$[EMAIL PROTECTED]...
