Here is a Perl function a friend of mine wrote to help with this...
Problems I ran into were errors because of NON NUMERIC Characters in the
String...
Casting would fail
It doesn't catch all cases but it has been quite helpful to me
$x = $_[0];
$x =~ s/^[^-\d\.]*//;
$x =~ s/\,//g;
$x = $x * 1;
return $x;
