Is there a keyword to express Infinity in Ruby?
If you use ruby 1.9.2, you can use:
>> Float::INFINITY #=> Infinity >> 3 < Float::INFINITY #=> true
Or you can create your own constant using the following*:
I've checked that in Ruby 1.8.6, 1.8.7, and 1.9.2 you have Float.infinite?.
PositiveInfinity = +1.0/0.0 => Infinity NegativeInfinity = -1.0/0.0 => -Infinity CompleteInfinity = NegativeInfinity..PositiveInfinity => -Infinity..Infinity
*I've verified this in Ruby 1.8.6 and 1.9.2
