I was surprised by your statement "No, it's not. It's a number, ...". You were responding to my assertion that the integer was already in binary and could be printed in different bases with printf. Yes, an integer is a number but that doesn't mean it is not stored as binary in memory. Are you referring to assigning a number to a scalar variable such as my $num = 42 ?

According to perlnumber an integer is represented in Perl as a native integer according to the C compiler used to build Perl. Maybe I have assumed Perl is more like C than it really is. I was referring to how it is stored in memory and that you can use printf to display the value in other bases or even in binary.

The OP was vague and didn't provide examples so I'm wondering how to know what the OP really wanted.
