Am I asking too much if I see something prints 3 the int of that to be 3 ?

In a word: yes.

int has a very clearly defined meaning: truncate to an integer. And that behaviour is required for many algorithms.

It never "rounds-up" as print does:

printf( "%.16f ", 3-$_ ), print 3-$_ for map 10**-$_, 1 .. 16;;

If you want rounding behaviour rather than truncation, use an appropriate function or module.
