PROJ/src/proj_math.h, branch 8.0

Delete proj_math.h. Replace includes by ; we'll see if anyone

2019-09-18T20:29:35+00:00

needs .  Update scripts/reference_exported_symbols.txt and
src/proj_symbol_rename.h.

math.cpp removed since its isnan isn't used. Keep proj_math.h (which

2019-09-18T18:25:15+00:00

just includes math.h and limits.h) since it's included in a score of
places.

Try removing C99 math functions from math.cpp (but leave isnan).

2019-09-18T11:08:55+00:00

Add atanh, copysign, cbrt, remainder, remquo to math.cpp.

2019-09-17T14:29:53+00:00

The supported C99 math functions provided by math.cpp are thus

   hypot
   log1p
   asinh
   atanh
   copysign
   cbrt
   remainder
   remquo
   round
   lround

Make compiler checks in CMakeLists.txt and configure.ac consistent with
this set.

Make geodesic.c use the math.cpp defined (instead of the internally
defined) versions of

   hypot
   atanh
   copysign
   cbrt

This is keyed off the presence of the PROJ_LIB macro.  I had at one
time

    https://github.com/OSGeo/PROJ/pull/1425

suggested supplying an additional macro PROJ_COMPILATION when compiling
geodesic.c.  However, PROJ_LIB seems to fill the bill OK.

The *next* version of geodesic.c (due out in a few weeks) will also use

   remainder
   remquo

All of this is only of concern for C compilers without C99 support.  So
this may become an historical footnote at some point.

Implement RFC 2: Initial integration of "GDAL SRS barn" work

2018-11-14T21:48:29+00:00

This work mostly consists of:
- a C++ implementation of the ISO-19111:2018 / OGC Topic 2
  "Referencing by coordinates" classes to represent Datums,
  Coordinate systems, CRSs (Coordinate Reference Systems) and
  Coordinate Operations.
- methods to convert between this C++ modeling and WKT1, WKT2
  and PROJ string representations of those objects
- management and query of a SQLite3 database of CRS and Coordinate Operation definition
- a C API binding part of those capabilities

This is all-in-one squashed commit of the work of
https://github.com/OSGeo/proj.4/pull/1040

Merge branch 'master' into return-nans-quickly

2018-05-23T11:41:08+00:00

Undef isnan if already defined before redefining it (typically with MSVC)

2018-05-19T12:10:08+00:00

Add round() and lround() to proj_math.h

2018-05-08T07:16:05+00:00

Add NAN definition to proj_math.h

2018-05-08T07:13:55+00:00

Move include of math.h inside include guard.

2018-04-30T19:58:06+00:00

No reason to include math.h more times.

And balance whitespace a bit
