	At least two such programs are available from netlib.  To quote from
the netlib index:

ELEFUNT is a collection of transportable Fortran programs for testing
	the elementary function programs provided with Fortran compilers.  The
	programs are described in detail in the book "Software Manual for the 
	Elementary Functions" by W. J. Cody and W. Waite, Prentice Hall, 1980.

PARANOIA is a rather large program, devised by Prof. Kahan of Berkeley,
	to explore the floating point system on your computer.

	"PARANOIA" comes in single and double precision versions for Fortran,
and there is a BASIC ;-) version too.  To see what is available send mail
to netlib@ornl.gov --

		send index from elefunt
		send index from paranoia
