PHP maths

Or, you could type cast...
$a = (int) $b / $c;

or...
$a = intval($b/$c);

To do this with sprintf, you'd use:
$a = sprintf("%d", $b/$c);

The problem with sprintf is that you've changed the datatype from a numeric (int, double, float, etc.) to a string. This isn't as big of a problem with PHP as it handles variant datatypes, but you'll have problems doing this in C/C++.

Thanks

Ok everything was going fine until I added a new entry (value of 0) now it's giving me a php warning:

Warning: Division by zero in c:\phpdev\....

anyway around this warning (short of turning error warnings off )
I tried all four methods mentioned above

I'm using negative, zero and postive numbers

b = whole numbers 0 ++ (no neagatives)
c = whole range (--1, 0, 1++)

a = c / b so insome cases the anser could be negative

It is a mathematical law that you can't divide a number by 0, but you can divide 0 by a number. Makes sense doesn't it??
So just remove the value of 0 for the variables... what exactly is their need here?

IF $b equals 0 (and is same datatype, numeric) THEN
$a = 0;
ELSE
$a = (int) $b / $c;
ENDIF

Thanks guys, nike_guy_man it's a vote form value thing, but to keep the number size down in the db I'm using -2, -1, 0, 1, 2 for the vote values then the values get added or subtracted from the old value and divided by the amount of values - if that makes sense.

Mark I'll give that a go tonight after work, thanks

I did some searching last night, anyone every use 'round' or 'ceil' or 'floor'

Yup..

round() will round to the nearest integer, unless you specify a precission (decimal places to keep).

ceil() round up to higher integer. no args.
floor() round to lower integer. no args.
