/* MathLib: Pilot shared library of IEEE-754 double math functions
 *
 * Convenience functions for the calling application.  These functions
 * provide a programmer-friendly wrapper around the raw system trap
 * invocations which actually call the library routines.  The idea
 * is to allow the programmer to say:
 *    y = sqrt(x);
 * instead of requiring:
 *	   MathLibSqrt(MathLibRef, x, &y);
 * like the system trap interface requires.  The system trap form is
 * not only harder to read, but can't directly replace the traditional
 * function call in ported code, and can't be nested inside an expression.
 * Just add this source file to your project or makefile, and include
 * "MathLib.h" in any source file that needs to call these.
 *
 * The downside to these routines is that they'll take up some space
 * in your program, though CodeWarrior at least is smart enough to
 * only link in the ones which you actually use, so it doesn't really
 * cost you that much.  In fact, if you call these enough they'll pay
 * for themselves, since "x=sqrt(x)" generates much less code than
 * calling MathLibSqrt() directly.
