roy asks,
What's the difference between the fractions with a diagonal line and the
ones with a horizontal line, or is it just cosmetic?
the ones with a diagonal line are used for things like recipe
books or in ordinary text  never in math. (and i like the
diagonal versions too, in the proper context.)
If there is a difference; does the base of the inferior
horizontallinedones sit on the baseline or can it sit on the descender
line?
i can't answer that in those terms. i'm not even certain where
the base sits for the ones with horizontal lines. however, the
horizontal line *should* line up with a minus sign and with the
horizontal member of a plus sign and the horizontal centerline
of the equals. if that's not done, then these fractions aren't
suited for use in math either.
roy  are you adding math stuff to fonts again?
