Re: Math::Round::Var::round() takes no action when a number is not supplied

in reply to Math::Round::Var::round() takes no action when a number is not supplied

It seems to raise a perfectly valid exception for me:

sub round { my $self = shift; my $rnd = $self->{precision}; my $number = shift; return(sprintf("%0.${rnd}f", $number)); };; print round( {precision=>3}, 1.23456 );; 1.235 print round( {precision=>3}, 1 );; 1.000 print round( {precision=>3} );; Use of uninitialized value $number in sprintf at ... 0.000

(Though quite why you'd use a module for this is beyond me?)

    Well, a Perl-generated warning is not the same as a program-generated exception, and here we have only a Perl-generated warning.

      Really? So how do you handle them differently?
