| 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. | |

| 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 | # | |
