Slightly odd Integer() behavior

Ruby
1

Integer(gets), works well if you enter any integer apart from 0, which
complains about “0\n” not being a valid integer. As expected,
Integer(gets.chomp) works for all integers, including 0.

Is it just me, or is this a tad bit weird? If it is not weird, then I
assume that I am weird for thinking it is weird so could somebody please
enlighten me on the source of my weirdness?

All this is happening on Ruby 1.8.6 running on an Etch/Lenny/Sid combo,
which I assume has nothing to do with the issue at hand.

For me (Windows2000) it works well for Ruby 1.8.6, but not for nightly
snapshot of Ruby 1.9…

type putsgets.rb
puts Integer(gets)
puts Integer(gets)
ruby -v
ruby 1.8.6 (2007-03-13 patchlevel 0) [i386-mswin32]

ruby putsgets.rb
5
5
0
0

ruby19 -v
ruby 1.9.0 (2007-12-02 patchlevel 0) [i386-mingw32]

ruby19 putsgets.rb
5
5
0
putsgets.rb:2:in Integer': invalid value for Integer: "0\n" (ArgumentError) from putsgets.rb:2:in’

I’ll post this in ruby-core because it looks strange.

Esta es una lista de discusion cuyo proposito es conversar acerca del
lenguaje de programacion Ruby, por lo general se plantean y resuelven
dudas.

Hay instrucciones para desuscribirse en el mismo lugar donde se dio de
alta, por favor sigalas y si no resultara vuelva a escribir explicando
que hace a mi direccion de mail personal si es tan amable.
