To add intrinsic functions or change them in the FORTRAN compiler:
1. Modify /usr/src/cmd/f77/intr.c of compiler if the type is to be
   set automatically by the compiler and several alternate C
   routines exist for separate types.
2. Put function source in this directory.
3. Add function name to makefile.

		Unix f77 Math Function Library
			February, 1981

This is the library providing interface to the C math library, libm.a
or libnm.a.(*) In addition there are functions for complex and double
complex arguments and short int arguments. There are also utility functions
to enable floating overflow/integer underflow trapping, and to return
numerical range for this machine. Finally there are also the string
functions required by ANSI plus a few additions.

Install these sources in parallel with the other f77 libraries. Then:
	make all
	make install

* This will eventually be a standalone math lib and will include argument
  range checking, etc.

Please send bug reports, fixes, etc. to one of
	dlw@g.cc.berkeley	(new uucp mailer)
	ucbvax!g.dlw		(old uucp mailer)
	g.dlw@berkeley		(arpanet)
