Convert Decimal to Fraction Imperial System

[harmor]

What this script does is take a number in decimal form (ex: 300.67) and converts it into a fraction for the imperial measuring system.

I looked for an already made script but to no avail so I made my own.

class Belts
{
	var $length;
	var $numerator = '';
	var $reduce = TRUE;
	var $denominator = 16;

function decToFrac()
{
	list ($whole, $numerator) = explode ('.', $this->length);

	$newlength = floatval('.'.$numerator) * $this->denominator;

	if($newlength > 0)
	{
		list ($floatwhole, $floatnumerator) = explode ('.', $newlength);

		$floatwhole = "$floatwhole.$floatnumerator";
		$floatwhole = floatval($floatwhole);
		$floatwhole = round($floatwhole);

		if((!$floatwhole&1))
		{
			if($floatwhole != 0){
			$gcd = $this->gcd($floatwhole, $this->denominator);
			$divnumerator = $floatwhole / $gcd;
			}
		}
		else
		{
			$divnumerator = $floatwhole;
		}

		if($floatwhole != 0)
		{
			while($this->reduce == TRUE)
			{
				$divnumerator = $divnumerator / 2;
				$this->denominator = $this->denominator / 2;

				if ($this->check_float("$divnumerator")){
					//echo "TEST: $divnumerator";

					$divnumerator = $divnumerator * 2;
					$this->denominator = $this->denominator * 2;

					$this->reduce = FALSE;
				}
			}
		}
	}

	/*echo "GCD: $gcd<br />
	Numerator: $divnumerator<br />
	Denominator: $divdenominator";*/

	//die($whole);

	if($whole >= 12)
		$whole = $whole / 12;

	list ($feet, $inches) = explode ('.', $whole);

	$inches = "0.$inches";
	$inches = floatval($inches);
	$inches = $inches * 12;
	$inches = round($inches);

	$divnumerator = round($divnumerator);
	$feet = floor($feet);

	if($whole < 12){
		$inches = $feet;
		$feet = "0";
	}


	$newlength = "$feet - $inches";
	if($divnumerator > 0)
		$newlength .= "&nbsp;<sup>$divnumerator</sup> / <sub>$this->denominator</sub>";

	return $newlength;
}

function gcd($m,$n)
{
	$_m=$m;$r=1;
	if($m<$n){$t=$m;$m=$n;$n=$t;}    
	while($r)
	{
		$r=(floor($m/$n)*$n)-$m;      
		$_n=$n;$n=$r;$m=$_m;
	}     
	return abs($_n);
}

function check_float($mVal)
{
  return ( is_float($mVal)
		   || ( (float) $mVal != round($mVal)
				|| strlen($mVal) != strlen( (int) $mVal) )
			  && $mVal != 0 );
}
}

Example of use

$belttech = new Belts;

//length always in inches
$belttech->length = 4.00;
echo $belttech->decToFrac();

Delete My thread please. I found a bug.
