Description Peter Quiring 2006-01-09 20:56:19 UTC 
Please describe the problem:
Certain large numbers are not properly displayed in the 64bit binary
represention area in scientific mode.

ie: 2 ^ 55 - 1

Steps to reproduce:
1. 2
2. x^y
3. 55
4. ENTER
5. -
6. 1
7. ENTER


Actual results:
Shows only bit 55 set (seems to ignore -1)

Expected results:
Show all bits set from 0 to 54.

Does this happen every time?
Yes

Other information:
Keep subtracting 1 until the binary display syncs with the decimal display. 
Any number from 55 to 64 seems to do the same.

Yup. Reproduced here. Ugh. I'll have a look at it tomorrow. Thanks.

Fix (hopefully) for the problem.

I rewrote the set_bit_panel() routine in gtk.c.
It no longer converts the displayed number to a
double then a long long, which is where the lose
of accuracy was occuring.

This also involved adding a couple of parameters
to the make_fixed() routine in display.c to make
it more generally useful for things like this.

Changes checked into CVS HEAD. Version number in configure.in
bumped to 5.7.21.
