Comp Freq

Key Comp Freq in Interpolation refers to the compounding frequency m that is needed to define the discretely compounded transform of the reference quantity, as described in Comp Linear
The number 0, which would normally mean simple compounding, is not supported.
Otherwise, 1 means annual compounding, 2 semiannual compounding and so on.

Note, m may be also set to a non-integer, positive number.
