William, Dima, thanks for these first microbenchmarks.
I agree, of course, that consistency, speed and precision are all important.
It sounds like keeping GSL as an option may still be desirable.
It may be possible to create a common base class RealDoubleElement_base and
have two implementation

Hi,
In addition to numerical correctness considerations, it is important
to also consider the impact on **performance**.

After looking a bit at gsl’s doc I don’t think there is any advantage to using
them if we are not using the error handling and reporting of gsl (by that I
mean error estimates on the results). The only interesting detail is, quoting,
“consistency across platforms”. If we are not doing high preci

Do you mean, specifically for RDF? (gsl is used in Sage's calculus/, not
only in RDF)

Elements of RealDoubleField (RDF) have some methods that are implemented
using GSL.
Would we be able to eliminate this dependency? Some of the functions, like
isnan, are available in the standard C library since C99. Do functions like
gsl_sf_sin have advantages over using functions from the mat
