Description:
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.
