6# This high quality math library is intended to run on either a VAX in
7# D_floating format or a machine that conforms to the IEEE standard 754
8# for double precision floating-point arithmetic.
9#
10# WARNING: On machines other than the ones mentioned above, run the original
11# Version 7 math library, if nothing better is available.

13#
14# MACH indicates the type of floating point hardware you are using; legal
15# values are:
16#
17# VAX		- for the VAX D_floating format, the default.
18# NATIONAL	- for those IEEE machines whose floating point implementation
19#		  has similar byte ordering as the NATIONAL 32016 with 32081.
20# IEEE		- for other IEEE machines, we hope.
21#
22MACH = VAX
