tvm calculations
Message #1 Posted by hugh steers on 5 Jan 2004, 10:35 a.m.
hi guys,
out of interest (ha!) i started looking into the computational problems underlying tvm calculations. getting correct answers isnt just a matter of plugging numbers into textbook formulae. which is why most (non-hp), so called, financial calculators get wrong answers except in straightforward cases.
the 12c and later models like 17bii/19bii have proven themselves stable in acquiring correct answers and i know there are still some discrepancies with results from the new 12cp.
anyway, the idea was to investigate some of the algorithms used and try to replicate correct answers. i wrote up some findings here; http://www.voidware.com/tvm.htm
any more ideas most welcome,
happy new year,
-- hugh.
