afair, double has 13 decimal digits precision, so your 697.04157958254996 represented by another value. you just looking for miracles
I think its 16 or 17 (significant not decimal digits). Its a miracle that Python achieves! But Haskell does not. Python uses doubles too, and for certain operations it uses arbitrary precision floating point (I think). Steve
