annuity functions

[igitur]

In all the Math utilities, i'm still missing the ability to write annuity functions correctly.

Annuity functions are often used in interest / actuarial calculations.

A typycal annuity function will look something like this

. a
. -
. n |

meaning, a lowercase a with an n subscript, and the n has a line above and to the right of it. The two lines touch in the corner. They shouldn't be two separate lines.

n can be replaced with many things, like Tx or Kx+1 etc, and the line above it will cover the entire piece of text.

I hope it will be included in future version.

regards,
Francois

Does anybody have any response on this?

I found that this feature is miss in OOoMath, so you can use

overline {some thing divides {}}

instead, but two lines are separated.
