/* NOTE: Because of the special way this file is used by <complex.h>, this
file must NOT be protected from multiple inclusion as header files
usually are.
This file provides prototype declarations for the math functions.
Most functions are declared using the macro:
__MATHCALL (NAME, (ARGS...));
This means there is a function `NAME' returning `double' and a function
`NAMEf' returning `float'. Each place `_Mdouble_' appears in the
prototype, that is actually `double' in the prototype for `NAME' and
`float' in the prototype for `NAMEf'. Reentrant variant functions are
called `NAME_r' and `NAMEf_r'.
Functions returning other types like `int' are declared using the macro:
__MATHDECL (TYPE, NAME, (ARGS...));
This is just like __MATHCALL but for a function returning `TYPE'
instead of `_Mdouble_'. In all of these cases, there is still
both a `NAME' and a `NAMEf' that takes `float' arguments. */
