Documentation

It says:

Almost all machines today (November 2000) use IEEE-754 floating point arithmetic, and almost all platforms map Python floats to IEEE-754 “double precision”. 754 doubles contain 53 bits of precision, [...]

That feels really weird, computer documentation written 22.5 years ago. I don't know what to think of that, whether that can be trusted today. I suggest to update that.

I also suggest to not start the next sentence with "754 doubles" but with "IEEE-754 doubles", both for style (don't start a sentence with a digit) and because it reads like a number of doubles instead of the kind of doubles (i.e., like "3 apples").
