Displaying text as proper Math

[Cudamine]

I want a mod that that turns (for example) the expression 2^3 as a proper looking power (2 to the power of 3), I saw another forum making use of a mod like this using tags, the tag converted any expression into what we're used to seeing on textbooks and whatnot.

Anything like this already up?

Thanks for your help!

Like you want to do this (2)³

It is already in SMF as SUB and SUP BB codes.
