#!/usr/bin/env perl
use warnings;
use 5.12.2;
my $c = 'f'; # could be a number too
if ( $c eq 'd' || $c == 9 ) {
say "Hello, world!";
}
What is the best way, to avoid the 'Argument "f" isn't numeric in numeric eq (==) at ./perl.pl line 7.'-warning?
I suppose in this case I could use "eq" two times, but that doesn't look good.
use Scalar::Util 'looks_like_number';
if ( $c eq 'd' || ( looks_like_number($c) && $c == 9 ) ) {
say "Hello, world!";
}
You could also disable this category of warnings temporarily:
{
no warnings 'numeric';
# your code
}
