Mel: Variable Conversion

String to int

string $stringVar = "100";
int $i = $string;

String to Evaluation

string $statement = "(99+1) / 2";
eval("float $dummy =" + $statement);

	//Eval Needs two values to evaluate
	//
	//so you need a second dummy variable to be 0. This
	//only works because it is a local variable, and is
	//re-initialized every time it is run.
	//
	//Unforunately, you cannot simply evaluate "eval(0 + $statement);"
