the library functions. The latter inline functions are only available
if the flag @code{-ffast-math} is given to GNU CC.
In cases where the inline functions and macros are not wanted the symbol
@code{__NO_MATH_INLINES} should be defined before any system header is
included. This will ensure that only library functions are used. Of
course, it can be determined for each file in the project whether
giving this option is preferable or not.
Not all hardware implements the entire @w{IEEE 754} standard, and even
if it does there may be a substantial performance penalty for using some
of its features. For example, enabling traps on some processors forces
