Formatting real world ratios and percentages

[Hexxx]

I am trying to make a function that would find the ratio of two number and return them in the format X.YY (because I would later need to format them in a table and align them).

I tried this

function divide ($numerator, $denominator)
{
  if ($numerator == 0 || $denominator==0 )
    return (round(0,4)*100);
  else
    return (round(($numerator/$denominator),4)*100);
}

But it's not working with whole numbers... it's displaying 1 instead of 1.00

Don't worry about the internal float representation of the data type. Look at the sprintf() function that converts to a string.
