What's the opposite of chr() in Ruby?
In many languages there's a pair of functions, chr() and ord(), which convert between numbers and character values. In some languages, ord() is called asc().
Ruby has Integer#chr, which works great:
>> 65.chr
A
Fair enough. But how do you go the other way?
"A".each_byte do |byte|
puts byte
end
prints:
65
and that's pretty close to what I want. But I'd really rather avoid a loop -- I'm looking for something short enough to be readable when declaring a const.
Answer
If String#ord didn't exist in 1.9, it does in 2.0:
"A".ord #=> 65
