Maybe you were thinking of 128 bit long doubles ?

we already use the 128 long doubles, the thing is we do a lot of accounting like
calculations and 'almost accurate' is not an option :-) i heard one can even
be sent to jail for that in the USA


64 bit integers work great for that matter, but we like to step up to more bits

the other tip i got was that we should look for

Sint128

but this type is unknow to gcc4.2 also

hi,

i setup a configuration in my project that uses gcc4.2 instead of gcc4.0
because i read that from gcc4.1 the compiler would support 128-bit integer
types


however:

	typedef int64_t pxlong;
//	typedef int128_t pxlong;


compiles ok, while

//	typedef int64_t pxlong;
	typedef int128_t pxlong;

gives an error saying 'int128_t' is not a type

what am i doing wrong here?

any help is very much appreciated
