[RESOLVED] convert a decimal to percentage ?

Pyrrhic

trying to make a shooting percentage for our team. Tried serveral variations but the one below is the best I could come up with is the number in a decimal form. .Even that is going 14 places. I would like for it to show as ??%

$p_array[$playerid][pave] = ($p_array[$playerid][goals]) / ($p_array[$playerid][saves]) * 100 ;

a point in the right direction would be greatly appreciated.

Are you trying to do this percentage for the whole team or trying to get a percentage for each individual participant ?

Perhaps you could show us some more code, how you are iterating through the arrays ?

Basically, you can already get the percentage you want, but you wanted it rounded to the nearest whole number. Use [man]round/man for that.

Tried to use round, number_format and a couple others but I am missing something when I use the . The page will go plank or will not change. But I take a look at it again. Also the first book u suggested, tnx. I have done alot of searching through this forum and many others, but I will continue

Trying to do the shooting percentages for individuals

Here is more of the array::

            $p_array[$playerid][goals] = $p_array[$playerid][goals] + mysql_result($result_stats,$sc,"goals");
            $p_array[$playerid][assists] = $p_array[$playerid][assists] + mysql_result($result_stats,$sc,"assists");
            $p_array[$playerid][ties] = $p_array[$playerid][ties] + mysql_result($result_stats,$sc,"ties");
            $p_array[$playerid][saves] = $p_array[$playerid][saves] + mysql_result($result_stats,$sc,"saves");
            $p_array[$playerid][shutouts] = $p_array[$playerid][player_stats.shutouts] + mysql_result($result_stats,$sc,"shutouts");
            $p_array[$playerid][minutes] = $p_array[$playerid][minutes] + mysql_result($result_stats,$sc,"minutes");
            $p_array[$playerid][yellow] = $p_array[$playerid][yellow] + mysql_result($result_stats,$sc,"yellow");
            $p_array[$playerid][red] = $p_array[$playerid][red] + mysql_result($result_stats,$sc,"red");
            $p_array[$playerid][gp] = $p_array[$playerid][gp] + 1;
            $p_array[$playerid][pts] = ($p_array[$playerid][goals] * $_CONF['goal']) + ($p_array[$playerid][assists] * $_CONF['assist']) + ($p_array[$playerid][ties] * $_CONF['tie']);

// FOR AVERAGES
$p_array[$playerid][pave] = ($p_array[$playerid][goals]) / ($p_array[$playerid][saves]) * 100;

This should do the trick, assuming the variables involved have the correct values:

// FOR AVERAGES
$p_array[$playerid][pave] = round(($p_array[$playerid]['goals']) / ($p_array[$playerid]['saves']) * 100);

PS: You really should quote your array index string literals (such as 'goals' and 'saves', above). Your code will probably process OK, but you leave open the possibility of very difficult to find bugs should you happen to define one of those strings as a constant in your code. (Also, the current behavior that allows you to get away with it now is not guaranteed to be maintained in future releases of PHP.) For more info, see, "Why is $foo[bar] wrong?"

That exactlly what I wanted. Tnx
I will take a look at the link you added and see how can apply your suggestion.
edited:: I see what you mean and I have begun to make those changes. tnx so much!!

tnx for the quick and percise answer to my initial question. round worked great. I wouldnt have thought of using it there.

Hey,

IF you don't have completly installed right I have many mods for hockey and the coding looks similar to what I have.
