Since the equation that you are trying to solve is a numerical function, using CAS functions will be very inefficient as you will be repetitively having to convert from CAS to non CAS. yes, I know, but in the program about IRR I needed to explore every result, not only the (only) numeric given by Solve.SOLVE... Mostly, well suited problems for IRR give only this result, and Solve.SOLVE is the better solution, but to test the problem I used some series of flows "at limit", where or IRR gives more solutions, or it's needed MIRR and not IRR... So, both solution "solve" the problem, depending on what happen... However, generally we treat (about IRR) lists (or matrix) with relatively few items (10100 max), so inefficiency is a problem that's "acceptable"...
