-/*							isnanl()
- *							isfinitel()
- *							signbitl()
- *
- *	Floating point IEEE special number tests
- *
- *
- *
- * SYNOPSIS:
- *
- * int signbitl(), isnanl(), isfinitel();
- * long double x, y;
- *
- * n = signbitl(x);
- * n = isnanl(x);
- * n = isfinitel(x);
- *
- *
- *
- * DESCRIPTION:
- *
- * These functions are part of the standard C run time library
- * for some but not all C compilers.  The ones supplied are
- * written in C for IEEE arithmetic.  They should
- * be used only if your compiler library does not already have
- * them.
- *
