#343 closed task (fixed)

standardize DEG2RAD() etc

Reported by: hamish Owned by: grass-dev@…
Priority: minor Milestone: 7.2.0
Component: Default Version: svn-develbranch6
Keywords: headers, coding style Cc:
CPU: All Platform: All



in the source now there is

misc/m.cogo/main.c:#define DEG2RAD(a) ((a) * M_PI / 180.0)
raster/r.param.scale/param.h:     #define DEG2RAD 0.017453293
raster/wildfire/r.ros/spot_dist.c:#define DEG2RAD 0.017453292
raster/r.flow/r.flow.h:#define DEG2RAD  0.0174532925199432958

it would be good to standardize these in gis.h just following the M_PI section. i.e. add these from m.cogo:

#define DEG2RAD(a) ((a) * M_PI / 180.0)
#define RAD2DEG(a) ((a) * 180.0 / M_PI)
#define DMS2DD(d,m,s) ((d) + ((m) / 60.0) + ((s) / 3600.0))
  • DMS2DD bug: if deg is negative (45:30S) -> -45 + .5 = -44.5

... or do the macros have to be in the same source file to be kept efficient?

Replying to hamish:

#define DMS2DD(d,m,s) ((d) + ((m) / 60.0) + ((s) / 3600.0))

  • DMS2DD bug: if deg is negative (45:30S) -> -45 + .5 = -44.5

nope, out->n_s is stored separately from out->lat in m.cogo. This is easy to forget, so dangerous to put in gis.h in hindsight.

Solved in r68881 (trunk) and r68882 (relbranch72) (without DMS2DD macro)

I'd suggest wontfix for GRASS GIS 6.

Since this was actually fixed, closing as fixed with different milestone.

To excuse the additional noise: I think closing as solved (if possible) is good for moral in general and understanding the history in this case.
