I spotted this ina piece of code I am trying to decipher, and it made me giggle...

Public Const INFINITE As UInt32

Infinity in an unsigned 32-bit Integer.

[Ryano121]

What value does it take on?

This one:

&HFFFFFFFFUI

[jon.kiparsky]

Negative 1 != infinity


(XFFFFFFFF represents a "quiet NAN" in IEEE floating-point representation, but this is an int, presumably twos-complement, so XFFFF FFFF would represent -1)

[Ryano121]

Interesting variable naming decision.

So, Infinity is in fact -1?

Excellent. I think we've just solved one of the world's biggest questions there. How big can infinity get? Apparently, not very

[jon.kiparsky]

INFINITY is negative 1. Which makes sense. If you start at zero and keep adding 1 forever, that's as far as you'll get...


BTW, my bad: I forgot that we're looking at an unsigned. So that's going to be just boring old 16^8-1, I guess.
