Thanks BP

The following is correct?
Giac is an iterated and recursive acronym for "Giac is a CAS", where the letter c is equal to CAS that stands for Computer Algebra System and the letter G related to the GNU project (free software)


Which arithmetic precision library does Giac use?

GMP (or MPIR), MPFR for multi-precision floats, MPFI for interval arithmetic.
It also works with tommath (significantly slower and support only multi-precision integers).
