Math & Science ⇒ Dotted fraction line?

[Sean]

Is it possible somehow to make the fraction line dotted instead of continuous? It would suit well if looked something like /cdots, but with the possibilty to write in the numerator and denominator.

[west.logan]

Is it merely for single digit numerator and denominator? If so, then you could define your own command. Otherwise it would take a bit more effort. Will it be used in both display mode and inline mode? I'm not aware of a quick method to change anything but rule thickness in the fraction. I would suspect you'd have to find the frac definition if you wanted to change to dots instead of a rule.

Indeed, for a single digit you could just use $\overset{a}{\underset{b}{\cdots}}$. For more complicated constructions, probably you could look at the dashundergaps package.

How long have you been working with (La)TeX Frabjous? You seem to have an answer to nearly everything. My experience is getting better, but still a bit mimsy...

[frabjous]

A couple years. 90% of what I know is from other members of this forum, however. But thanks!

[Sean]

Thanks a lot, the dashundergaps package solved it.

Code: Select all

\[{\dotuline{a+b}\atop c+d}\]
