found a solution

[belovedcrown.livejournal.com]

found this solution online to trim the excess decimals caused by the floating point error, but it doesn't round, which means the total pricing for each item i am trying to calculate may be off by a penny:

function dp(price)

{

string = "" + price;

number = string.length - string.indexOf('.');

if (string.indexOf('.') == -1)

return string + '.00';

if (number == 1)

return string + '00';

if (number == 2)

return string + '0';

if (number > 3)

return string.substring(0,string.length-number+3);

return string;

}

can someone help me make this round?
