2018-10-06Make PROJ_HEAD descriptions more uniformIvan Veselov
Before that, approximately half of the descriptions had a period at the end, e.g. 'Cyl.' or 'Sph.' and the other half did not have those periods. This commit drops all the dots in PROJ_HEAD descriptions.
2018-04-16Collect custom C99 math functions in proj_math.hKristian Evers
We are relying more and more on C99 math functions. On C89 systems where those functions are not available our own custom versions of those functions are used instead. So far these has been spread across the code base. This commit gathers them in the same file and introduces the proj_math.h header. The build system checks for C99 math functions. If not found the proj_math.h header make sure that C99 functions are defined as their pj_ equivalent. Ideally proj_math.h is included instead of math.h. This removes the need for any checks against HAVE_C99_MATH in the code making it easier to read. For this commit the functions hypot, log1p and asinh has been taken care of.
2018-03-11Remove angle brackets for proj headers (#849)Thomas Knudsen
* Avoid using angle brackets for PROJ headers. Switching from #include <proj.h> to #include "proj.h", and correspondingly for projects.h and proj_api.h, reduces the risk of accidentally picking up a system installed older version of the header while building a new version of PROJ. * Also handle geodesic.h
