This one works... Message #2 Posted by Gene on 28 Apr 2006, 10:17 p.m., in response to message #1 by Gary http://www.rskey.org/gene/hpgene/tvm19c.htm

Re: Financial Program for the HP-15C Message #4 Posted by Karl Schneider on 29 Apr 2006, 10:03 p.m., in response to message #1 by Gary Gary -- A quote from Gene's HP-29C program description: Quote: This program is not very sophisticated when it comes to solving for the interest rate and can take up to a minute or so to find it. For all but bizarre financial problems, however, it should be OK. Be patient. If you have the HP-34C applications book, you really should use the program in it for TVM: it uses the Solve function for the interest rate. This is correct, because among the five floating-point variables (N, I, PV, PMT, FV), interest rate "I" is the only one for which cannot be expressed as a closed-form algebraic equation -- numerical iteration is necessary. The following TVM applications under "Annuities and Compund Amounts" utilize SOLVE, and are quite well-suited to the HP-15C. They can be found in the following manuals: HP-15C Advanced Functions Handbook (MoHPC CD #1 or DVD), pp. 26-39. HP-34C Applications book (MoHPC CD #4 or DVD), pp. 27-37. -- KS Edited: 29 Apr 2006, 10:05 p.m.
