[Flashforth-devel] User Cfunction with double math returning 2 float results

[om1zz <om...@vo...>]

Hi,
in

https://github.com/igor-m/EXPERIMENTAL_ZZ/blob/master/examples/Cfun/Cdistbear1.c

you may find a demo which calculates distance(m) and bearing(deg) of two points on Earth called as a single user Cfunction,
with float arguments (lats, longs), calculating with doubles, and returning 2 float results - distance and initial bearing.
