How do you set to Double Precision mode for 34S? - zeno333 - 01-16-2017 02:10 AM
How do you set the 34S to Double Precision mode...I know its probably in the documentation, but cant seem to find it. RE: How do you set to Double Precision mode for 34S? - Paul Dale - 01-16-2017 03:35 AM
In the MODE catalogue. Press D and you'll get to DBLOFF, you want DBLON which is immediately below. Pauli RE: How do you set to Double Precision mode for 34S? - zeno333 - 01-16-2017 04:15 AM

Perhaps you need the manual - Pauli RE: How do you set to Double Precision mode for 34S? - Leonid - 01-16-2017 04:49 PM
BTW there is no way to programmatically displays the 18 trailing digits in DP mode? RE: How do you set to Double Precision mode for 34S? - Paul Dale - 01-16-2017 09:37 PM
I'm sure a program could be written to display the extra digits: To get the second 12 digits: set round to zero mode, round to 12 digits, subtract from the original number. Do this again to get the final 10 digits. Pauli RE: How do you set to Double Precision mode for 34S? - Dieter - 01-17-2017 08:36 PM

The round mode is set by the RM command which is part of the MODE menu. (01-16-2017 09:37 PM)Paul Dale Wrote: round to 12 digits, Round to 12 significant digits. This is accomplished by the RSD command that can be found in the X.FCN menu. (01-16-2017 09:37 PM)Paul Dale Wrote: subtract from the original number. Yes. ;-) So all in all it's a procedure like this: Code: `RM 4 // set round mode to truncation` Dieter |
