$abcd = round($rate_yes / $rate_no * 100);

rating for both fields are +1(s)

anyone know how to tell this to tell me the percent out of a 100%

Right now this shows me % like 157%..etc I want it to be out of a 100%


so for
rate_yes = 10
rate_no = 7
Thats the votes that are logged in the DB.
the real % comes out to 157%, but how do I get it to come out to a percent by 100% so it cant go over

Thanks

a little math would be helpful … ask yourself, what exactly is represented by 100%? is it $rate_yes, $rate_no or something else.

Okay, any help on leading me to correcting that? Out of 17 votes, 10 people liked it, just need it to read the percent of that out of a 100% ?

so you need to translate 10 / 17 into PHP code …

$rate_t = $rate_yes + $rate_no;
$abcd = round($rate_yes / $rate_t * 100);

Believe that's the correct idea now. Sorry like 5am over here, but i'll get it ;)
