Pray tell, what kind of a thing IS the size
of an infinite set, if not some kind of infinite number? If it's not a number,
what is it doing in mathematics? This just seems like a silly question.

So, it's just a placeholder for where you might have a number, but you don't
have a number, so it's NaN. Real great. What kind of math can you do on a Java
NaN?

Pretty much the same arithmetic operations you can do on Math.INFINITY
in Java. An arithmetic operation involving a NaN results in a NaN, and
similarly any operation involving an infinity operand results in either
an infinity or a NaN.

But you're not using Java floating-point arithmetic as a basis to
explain abstract mathematics, are you?



Why don't you ask Brian why he compared infinite set sizes to NaNs in Java?
That wasn't MY suggestion, that's for sure, as you could easily see from the
post you responded to but overtrimmed.

BTW, I think floating point sucks. :)
