Re: "Cast" a wxString to Numeric?

Do you really want to treat the empty string as zero? If so, I would simply be more explicit about it:

my $numerator= $IcqText->GetValue;
if( $numerator eq '') { $numerator= 0 };
$self->{AMP1}->Icq( $numerator / 1000 );

Corion, thanks for your reply. Yes, I think I need to go with your suggestion. The event gets triggered every time the TextCtrl is modified and if you backspace until you erase the entire entry the value will end up "" which needs to be interpreted as 0 for my purposes.
