(Free42) Utilities to view all digits
These utilities show all 34 digits of a number in scientific notation.
All are written specifically for Free42, relying on its blazing speed.

1.SMX: split a number into signed mantissa and exponent


A subroutine used in all utilities

In:
X: s.m.10^x
Out:
Y: s.m
X: x

Code:
00 { 48-Byte Prgm }
01>LBL "SMX"
02 ENTER
03 XEQ 10
04 RCL ST Y
05 SIGN
06 x
07 X!=0?
08 STO/ ST Y
09 X<>Y
10 X!=0?
11 LOG
12 RTN
13>LBL "MANT"        subroutine courtesy of Dieter
14>LBL 10        s.m.10^x -> m
15 ABS
16 1
17 X<Y?
18 10^X
19 /
20 ENTER
21 X!=0?
22 LOG
23 IP
24 10^X
25 /
26 1
27 X>Y?
28 10^X
29 x
30 END

2.SHOW: Show all digits in ALPHA

A straightforward approach using the Alpha register:
will only work for reals.

Code:
00 { 50-Byte Prgm }
01>LBL "SHOW"
02 ENTER
03 CLA
04 XEQ "SMX"
05 X<>Y
06 AIP
07 ABS
08 FS? 28
09 +"."
10 FC? 28
11 +","
12 FP
13>LBL 10
14 10
15 x
16 AIP
17 FP
18 X>0?
19 GTO 10
20>LBL 00
21 Rv
22 +"E"        this is the small exponent E
23 AIP
24 AVIEW
25 Rv
26 END

3.D30: shows the 30 least significant digits in the menu.

.grouped digits make for easy reading
.small font
.handles real, complex, matrix (both real and complex)

Use EXIT for exiting.
When a complex number is shown, pressing any menu key will switch between real and imaginary part. You can use the built-in SHOW (shift-RS) to show 12 digits of both parts.
When a matrix is shown, use up and down arrows to navigate the matrix in a column-wise manner.

Code:
00 { 165-Byte Prgm }
01>LBL "D30"
02 CLMENU
03 KEY 9 GTO 09
04 MAT?
05 FS? 31        Always False Filler

4.SB: Stack Browser

.shows X and Y stack levels at the same time
.use ENTER to alternate between most significant and least significant digits
.only reals, shows "NaN" for anything else
.medium font (4x6)
.use UP and DOWN arrows (or Rv) to roll up and down respectively.
.use Backspace (<-) to exit.

   
   

No listing provided as it's full of special characters..

Attachments contain all programs in .raw format
