Fraction problem

[ligraci]

Hi,
how can I convert a fraction in a decimal number? Is there a php function for this?

If so, how can I transform a string var of an html form in a fraction? I mean that I type 1/2 in an html form text but I want php considers it like a fraction number.

Any help?

Thanks ^_

You could try casting it as a number....or .5??

Ok - I suck and can't read. The above link will convert a decimal to a fraction, which could be handy...

function fractionToDecimal($fraction)
{
	$expFrac = explode('/', $fraction);
	return $expFrac[0]/$expFrac[1];
}

Or another way... Although this one doesn't do any type checking so it could be possible to use it for evil:

function fractionToDecimal($fraction)
{
  return eval('return ' . $fraction . ';');
}
