octave: liboctave/util/oct-inttypes.cc annotate

annotate liboctave/util/oct-inttypes.cc @ 22079:e0dbd81fd9b1

provide wrapper for frexp and frexpf (bug #48363) * bootstrap.conf (gnulib_modules): Add modules frexp and frexpf. * liboctave/wrappers/math-wrappers.c, liboctave/wrappers/math-wrappers.h: New files. * liboctave/wrappers/module.mk: Add math-wrappers.{c,h}. * lo-mappers.cc, lo-mappers.h (octave::math::frexp): New functions. (octave::math::log2): Use them instead of std::frexp. * data.cc (Feps): Use octave::math::frexp instead of std::frexp. * oct-inttypes.cc (dblesplit): Likewise.
