FPCE (Floating-Point C Extensions) of C9X (the revision of C currently in
progress) has defined behaviour of the math library functions for IEEE-754
values and exception flags.
LIA-2 (Language Independent Arithmetic Part 2: Elementary numerical
functions) has accuracy requirements on the math library functions
as well as behaviour for exception cases.
