Haskell-friendly exports.

c_swe_revjul :: CDouble -> GregFlag -> Ptr CInt -> Ptr CInt -> Ptr CInt -> Ptr CDouble -> IO () Source #
Reverse of c_swe_julday: produce a gregorian date
c_swe_calc_ut :: CDouble -> PlanetNumber -> CalcFlag -> Ptr CDouble -> CString -> IO CalcFlag Source #
Calculate the position of a body, given a time in
Universal Time. Note that this is marginally more expensive than
swe_calc, but I use this one to keep consistency with swe_houses.
c_swe_houses :: CDouble -> CDouble -> CDouble -> CInt -> Ptr CDouble -> Ptr CDouble -> IO CInt Source #
Get the house cusps and other relevant angles for
a given time and place. Note that there's also a
swe_houses_armc if one happens to have the ARMC
and the ecliptic obliquity handy from other calculations.
c_swe_house_pos :: CDouble -> CDouble -> CDouble -> CInt -> Ptr CDouble -> CString -> IO CDouble Source #
Calculate the house a planet is in. Takes into account obliquity of the ecliptic. Works for all house systems, except Koch.
c_swe_cotrans_sp :: Ptr CDouble -> Ptr CDouble -> CDouble -> IO () Source #
Low-level function to translate between coordinate systems, with speed position included.
c_swe_split_deg :: CDouble -> SplitDegFlag -> Ptr CInt -> Ptr CInt -> Ptr CInt -> Ptr CDouble -> Ptr CInt -> IO () Source #
Split a given ecliptic longitude into sign (number) degrees, minutes and seconds.
c_swe_deltat :: CDouble -> IO CDouble Source #
Calculate the delta time for a given julian time,
delta time + julian time = ephemeris time
NOTE: there's also swe_deltat_ex which takes an ephemeris
flag explicitly, vs. the current global value.
my calculations work in one ephemeris, so this one is suitable.
