This represents what type a float arg is passed as. It is used when the type is
not promoted to double.
__OBSOLETE_MATH_DEFAULT
Default value for __OBSOLETE_MATH if that's not set by the user.
It should be set here based on predefined feature macros.
__OBSOLETE_MATH
If set to 1 then some new math code will be disabled and older libm
code will be used instead. This is necessary because the new math
code does not support all targets, it assumes that the toolchain has
ISO C99 support (hexfloat literals, standard fenv semantics), the
target has IEEE-754 conforming binary32 float and binary64 double
(not mixed endian) representation, standard SNaN representation,
double and single precision arithmetics has similar latency and it
has no legacy SVID matherr support, only POSIX errno and fenv
exception based error handling.
