What/Where is Infinity and NegativeInfinity?

I see Infinity and NegativeInfinity being referenced in BoxedFloat64.

'From Cuis7.1 [latest update: #6472] on 23 June 2024 at 11:31:09 am'!

isInfinite
     "Return true if the receiver is positive or negative infinity."

     ^ self = Infinity or: [self = NegativeInfinity]! !

But when I try to "Do it" in the Workspace, it returns unknown variable.
