in thread I prefer my indexes to start at:

Apparently, the totalOrder predicate from IEEE 754-2008 specifies that -NaN < -Inf < negative finite numbers < -0 < +0 < positive finite numbers < +Inf < +NaN.
So if floating point values are allowed, then I think that "-Nan" would be the obvious starting point ... coz you can't not get no lower than that ;-)

(Hopefully, indexes have to be real integer values.)

Cheers,
Rob

"Hopefully, indexes have to be real integer values." I don't see that they have to be "integer" values, but it gets tricky for current hardware if they aren't limited precision rational numbers. In fact even "integer values" is a deal breaker if they aren't limited precision. Optimising for fewest key strokes only makes sense transmitting to Pluto or beyond	[reply]

"Integer value" is a rather abstract concept. It has nothing to do with precision or how we represent it (even on paper). Bill	[reply]
