Description Dennis Schridde 2019-03-31 21:55:12 UTC
The flag is commonly called "double-precision" by other ebuilds:
$ q use -D double
 local:double:sci-libs/libccd: Use double precision floats.

$ q use -D double-precision
 local:double-precision:dev-games/ode: more precise calculations at the expense of speed
 local:double-precision:dev-games/ogre: More precise calculations at the expense of speed
 local:double-precision:games-sports/xmoto: more precise calculations at the expense of speed
 local:double-precision:media-libs/aubio: Compile in double precision mode.
 local:double-precision:media-sound/csound: Use double-precision floating point for audio samples
 local:double-precision:sci-biology/fasttree: use double precision instead of single-precision floating point (2x memroy required)
 local:double-precision:sci-chemistry/eden: More precise calculations at the expense of speed
 local:double-precision:sci-chemistry/gromacs: More precise calculations at the expense of speed
 local:double-precision:sci-libs/parmetis: Floating-point operation done as double precision
 local:double-precision:sci-physics/bullet: Build libraries in double precision
