Subject: ODFF: RRI function
1. "Summary: Returns the interest rate resulting from the profit (return) of an investment" That's more or less copied from Calc Help, and doesn't really illuminate. How about: "Returns an equivalent interest rate when an investment increases in value." 2. Typo: N and P are both used for number of periods - need one or the other. 3. "N is NOT truncated to an integer" - that's OK, but it might be wise to note that for fractional N the result is slightly inaccurate, as a partial period does not partially compound. 4. I wonder if this function should really be included in ODFF? Calc has it, but Excel does not. It's a simple formula calculation, and you need to understand the formula to use it anyway. D PS I'm almost through looking at functions (as part of another task), so this may be the last of these notes. Hope they are useful.
