Hi everybody,
I'm trying to check weather a variable is an integer, i have tried the
following:
use Math::BigRat;
my $x = 42;
print "$x is an integer\n" if $x->is_int();
But it doesn't work, it gives me the error:
Can't call method "is_int" without a package or object reference at
test.pl line 3.
Can somebody give me a hint what i am doing wrong, or is there a better
way to check if a variable is numeric ?
Thanks
Mads
