Hi.

I'm working on making it possible to change the size units in the label
editor and the fdisk editor.

Inevitably, I must use bytes instead of sectors to represent the sizes.

The problem is that this overflows tcl's default integer type (long):

anarcat@shall[~/libh/release/diskedit]% bc=20
bc 1.06

anarcat@shall[~/libh/release/diskedit]% tclsh8.3
% expr 60030432 * 512
670810112
% expr 30735581184
integer value too large to represent

I guess the proper solution is to use a floating points, but that seems
evil to me...

Unless anyone has a better idea, i'll use floating point. Or at least
try. ;)

A.
