calculation of astronomical functions with arbitrary precision

(1) Stellar astrophysics: Calculate L and R from V, T and parallax

(2) Binary: Calculate R sin i [or inclination] from Prot, vsini [and R]

(3) Orbit: Calculate M2 from M1, f(M) and i

(4) Orbit: Calculate K2 from K1, M1 and M2

(5) Orbit: Calculate a1 and f(M) from P and K1

(6) Roche lobe radius RL [and log g] from M1 and M2 [and R]
