A recent proposal on the python-ideas mailing list would add a new way to represent floating-point infinity in the language. Cade Brown suggested the change; he cited a few different reasons for it, ...

Anybody who has ever taken a numerical analysis course understands that floating-point arithmetic on computers is a messy affair. Even so, it is easy to underestimate just how messy things can be.

An unfortunate reality of trying to represent continuous real numbers in a fixed space (e.g. with a limited number of bits) is that this comes with an inevitable loss of both precision and accuracy.

Why floating point is important for developing machine-learning models. What floating-point formats are used with machine learning? Over the last two decades, compute-intensive artificial-intelligence ...
