double-precision logs with error bounds
multiply by inverse
mag methods for powers, factorials, bernoulli numbers (work in progress)
add arf_set_d, arf_get_d
add arb_rising_fmpq_ui
add acb rising factorials
port most gamma function code to arb/acb
port rising2 methods
port digamma function
port gamma function power series methods
don't use the libm log
use mag methods for hypgeom bounding code; add arb_hypgeom_sum methods
port most arb_const_ methods
port the last of gamma_fmpq and add test code
minor cleanup
port most of the zeta function code
port remaining zeta methods
port some of the bernoulli number code
use new types for bernoulli iteration code
port sin, cos, sin_cos
