Hi Monks,

I have a question regarding Perl's numeric type, and how (I assume) it simplifies the value before storing/printing them.

For example:

use warnings;
my $foo = 50.0;
warn $foo;

[download]

would display 50, rather than 50.0. I'm interested in knowing if this is always the case (can I rely on this behaviour of simplifying the number?), where can I read more about this if it is documented. I tried searching for more information in https://perldoc.perl.org/perlnumber but I couldn't find anything specific to this.

I am only interested because I find this an easy way to remove trailing decimal zeroes, and if I can get away with not using sprintf then that would be great.
