Initially some of these were found building the unix coverage variant on MacOS because that build uses clang and has -Wdouble-promotion enabled, and clang performs more vigorous promotion checks than gcc. Additionally the codebase has been compiled with clang and msvc (the latter with warning level 3), and with MICROPY_FLOAT_IMPL_FLOAT to find the rest of the conversions. Fixes are implemented either as explicit casts, or by using the correct type, or by using one of the utility functions to handle floating point casting; these have been moved from nativeglue.c to the public API.
