[WP34s] derivatives and display mode Message #23 Posted by Dieter on 10 Mar 2013, 11:20 a.m., in response to message #1 by Richard Berler
Richard, it would be nice if you would choose a more meaningful subject. Else we will end up with a dozen different threads all titled "WP 34S". ;-)
I tried your example on a (hardware) 34s running version 3.2 3360, without a custom defined delta-x, and the result was always the same:
LBL 01
f'(x) 00
RTN
LBL 00
x^2
RCL L
e^x
/
RTN
1 [ENTER] 3
SLV 01 => 1,999 9999 9999 8726
Which is displayed as
2,0000 in FIX 04
2,0000 0 in SCI 04
2 in ALL 03
Defining delta-X = 0,0001 yields one more valid digit:
1,999 9999 9999 9809
Again, independent from the display setting.
