#
# This high quality math library is intended to run on either a VAX in
# D_floating format or a machine that conforms to the IEEE standard 754
# for double precision floating-point arithmetic.
#
# WARNING: On machines other than the ones mentioned above, run the original
# Version 7 math library, if nothing better is available.
#
# HARDWARE indicates the type of floating point hardware you are using;
# we use MACHINE because we don't have anything better.
# Current legal values are:
#
# vax           - for the VAX D_floating format, the default.
# tahoe         - for the TAHOE double format.
# national      - for those IEEE machines whose floating point implementation
#                 has similar byte ordering as the NATIONAL 32016 with 32081.
# ieee          - for other IEEE machines, we hope.
