How about... "Nan" is a string representation of the floating point literal NaN. Like all string representations of floating point numbers it may be treated as it's numeric value. However, "not a number" is a non floating point string, so is treated as 0. Gaak! Trying to say this succinctly is a great way to twist your brain into knots. Disclaimer: IANALL, but I've played one in several companies.<grin/>
