/* mathl.h
Definitions for the long double version
of the math floating point package.
Copyright (c) Borland International 1989

*/
/*----------------------------------------------------------------*\
This file is a modification of <math.h>, with declarations for
long double functions as recommended by ANSI X3J11. All of the
functions below are currently supported.
Error handling is somewhat different from the TC <math.h>
functions, but within the ANSI guidelines. If <math.h> function
have a domain or range error, _matherr is called, and errno is
set. The functions in this file do not call any error handlers
or set errno. When an overflow or underflow occurs, infinities
and zeroes are used appropriately. If no reasonable value can be
found, NAN (Not-A-Number) is used.
