Re: Lua5 / poor performance

["Russell Y. Webb" <rw20@...>]

So IEEE floats have some duplication in bit representation based on the 
sign bit.  Integers of course have a 1 to 1 representation.  How about 
just using this code to hash all numbers?

TObject *o;
lua_Number n_to_hash = o->value.n;
if(n_to_hash < 0){
	n_to_hash = -n_to_hash;
}
HashMemory(&n_to_hash, sizeof(n_to_hash));

Seems to handle all sensible number types and only causes automatic 
collisions of pairs of numbers with the same absolute value (rather 
than a myriad of numbers all having the same integer part).
