Binary package “gap-float” in ubuntu xenial
multi-precision floating-point computation for GAP
GAP is a system for computational discrete algebra with particular
emphasis on computational group theory, but which has already proved
useful also in other areas.
.
This GAP package brings to GAP floating-point numbers with arbitrary
precision; it is based on MPFR, MPFI, MPC, CXSC, and FPLLL.
