I'm guessing Perl automagically chomps them when doing mathematical operations?

yeah, see Re: Incrementing "Infinity" bug (numification, perlnumber, magic increment decrement), perlnumber, perldata, Infinity and Inf?, atoi, atof, strtod, Is this odd behavior a floating point problem?, What Every Programmer Should Know About Floating-Point Arithmetic or Why don’t my numbers add up?

Should I chomp them manually got style?

Its What? See below

Also, anything also "wrong", or could be done better with my code?

You can do the chomping in your sub input, so you don't have to remember to do it later

Aside from that looks great for a beginning programming exercise

For other approaches see Term::Interact example, dispatch table,
