Re: How can I test for the representation of an integer?

Thanks to Autobox you can do

use autobox::universal qw(type);

say type("42");  # STRING
say type(42);    # INTEGER
say type(42.0);  # FLOAT 
say type(undef); # UNDEF

Thanks - that's probably the most accessible way I've seen. Feels like it should be in Scalar::Util.	[reply]

Feels like it should be in Scalar::Util I don't think I would trust Scalar::Util to not fiddle about with the wrapping. For example, Scalar::Util's looks_like_number() returns true for a Math::BigInt object, even though the looks_like_number() XS function would return false. Cheers, Rob	[reply]

Thank you, very useful! I ended up with this: `if (eval {require autobox::universal;}) { autobox::universal->import('type'); } else { print 'Warning: Cannot locate autobox/universal.pm in @INC (you may + need to install autobox)' . "\n" . "In Strawberry Perl you can get autobox like this:\n" . " 1. from a Windows Administrator (elevated) command prompt +...\n" . " 2. cd \\strawberry\\perl\\bin\n" . " 3. cpan autobox::universal\n\n"; eval("sub type { return '?';}"); }` [download]	[reply] [d/l]
