Sure calculating infinity is easy as long as you redefine "infinity" to be something which isn't actual infinity. But it's useless for many mathematical proofs.

Sure calculating infinity is easy as long as you redefine "infinity" to be something which isn't actual infinity. But it's useless for many mathematical proofs. Having overflow of some finite floating point calculations labelled as "infinity" is useful for calculations of some practical problems, but it shouldn't be confused with the actual mathematical concept of infinity just because both use the same word.
- thaumasiotes 4y agoFloating point infinity is "actual infinity". It has all the correct mathematical properties. If you want to slam a special IEEE constant, you should slam 0, which has different properties from mathematical zero.
