octave: liboctave/numeric/lo-mappers.h annotate

annotate liboctave/numeric/lo-mappers.h @ 23682:6fe13cd3543c

Clean up lo-mappers.h, lo-mappers.cc. * lo-mappers.h: Remove using std::FUNCTION lines. Prefer to specifically declare std:: namespace at point in code where function is used. Specifically call std::ceil rather than just ::ceil which leaves it up to the linker. * lo-mappers.cc: Add explanatory comments to code. Use constants from math.h rather than calculating our own. Place frexp code in alphabetical order in list of functions. Call std::acos, std::asin rather than ::acos, ::asin which leaves decision to linker. Use all upper case for constants in code. * lo-specfun.cc: Replace asin with call to std::asin so that code compiles.
