[lmi-commits] [lmi] master 6b06fd4 2/6: Use standard <cfenv> macros with standard <cfenv> functions

[Greg Chicares]

branch: master
commit 6b06fd45bc5c15de2018d20281723fc51a9f07d6
Author: Gregory W. Chicares <address@hidden>
Commit: Gregory W. Chicares <address@hidden>

    Use standard <cfenv> macros with standard <cfenv> functions
    
    At present, comparing an lmi enumerator to std::fegetround()'s result
    was not an error, but only because the enumerators are contrived to
    have the same names as the macros. However, that contrivance is quirky
    and fragile, and it requires <cfenv> to be included in 'fenv_lmi.hpp',
    whence it leaks broadly, making it harder to sequester <cfenv> as an
    implementation detail and encourage lmi's equivalent but more robust
    facilities to be used instead.
