<H1>Currency Convert class Selector</h1>
The goal of this tool is to help you use the CurrencyConvert class by selecting class parameters using a web form.<br>
Once you've selected your parameters, you obtain the PHP code to insert in your page as well as a sample of the conversion : how roundings and rates are handled.<br>
As you can see, rounding can be finely tuned using the kind of rounding.<br>
That way, you can define conversion rules like "convert $ price to DM using a 0.5 DM superior rounding", etc.<br>
<?
	if (isset($show)){
	include('class_currency_convert.php');
	$conversion=new CurrencyConvert($rate,$rounding,$roundType,$nbDecimal,$idFrom,$idTo);
	echo '<H2>Result :</h2>';
	echo "<ul><li>Conversion from $value in '$idFrom' to a value in '$idTo': ";
	echo $conversion->getValue($value)."<br>\n";
	echo " ( getStringValue($value) = ".$conversion->getStringValue($value)." )<br>\n";
	echo '</ul>';
	echo '<ul><li>PHP code : <pre>';
	echo "object = new CurrencyConvert('$rate','$rounding','$roundType','$nbDecimal','$idFrom','$idTo');";
	echo '</pre></ul>';
