#racket

while trying out extfloats in plt racket I noticed that some extfloats were returning different numbers from float and regular integer arithmetic

is this normal behavior?

For example, when comparing fl->exact-integer for flonum calculations vs. mixed integer calculations, = reports #t

however, when comparing extfl->exact-integer vs. mixed integer calculations, = reports #f

Hmm. As it turns out, defining a new kind of easy-syntax immutable data structure is harder than I expected. Go figure ...

anybody got anything?

I just looked athe number generated by extflonums and it's different from the one I got from wolfram alpha as well.

Maths is sadly not my area.

well, i think this difference in calculation's pretty serious.

I don't know if SSE on my processor is busted, if the numbers should be different (possibly * is using floating point operations), or if racket's mangling something.

Might be worth filing an issue, that does seem like a problem indeed.

J_Arcane: I guess I'll do that; thanks a lot!
