UDF not needed. Enter formula into a cell:
=2^1/12

(Set the value of the cell to 2 raised to the 1/12th power. This is a
one-time calculation, unless you can define the problem a bit more.)

hi,

i need a udf or nested function that will give me the 12th root of 2.
This value is important for music stuff and I could use a udf that give
it to me exactly.


thanks
