That's a vexing question 'cos you just gave a comprehensive list of them.
Perhaps numeric.c is the answer you wanted ?

( In<i>finity spelling irrelevant )
Infinity is simulated all the way AFAICT  so, with your help,
I think this shows that your definition usably sticks:
negi = (1.0/0.0)
p negi # Infinity
Infinity = negi
p Infinity # Infinity
p Infinity.class # Float
p Infinity == (+1.0/0.0)1 # true
Without all that unnecessary fuss:
Infinity = (+1.0/0.0) # set constant
x = Infinity3
p x # Infinity
