# 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.
#
# MACHINE indicates the type of floating point hardware you are using; 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.
