To make way for an eventual upcoming feature whereby the user can select
the minimum fractional inch value (1/8", 1/16", 1/32", etc) to be
displayed, the function responsible for rendering this string was
rewritten. Previous functionality used hardcoded values for 1/8" and
therefore did not allow this to be changed. New code will work with any
integer denominator.
Also, a minor bug in the previous implementation has been fixed by the
new code. Prior to this fix, if an inch value rounded up to a foot, it
would still be rendered in inches. For example: 23.99" would be rendered
as 1'+12". The new code will render this as 2'.
Default fractional value set to 8 (1/8") for now such that there is no
change in the existing behavior. GUI option will be added at some point
in the future.
Independent of scale, use only mm/min or in/min because it is compatible
with GCODE feed rate units.
(My use case is definition os feed-rates in PathLoadTool.py).
