[WP34S] Once Working TVM Now Broken Message #1 Posted by Les Wright on 7 May 2012, 1:15 a.m.
The TVM library routine was working very well thanks to improvements to the solver, but when I revisited tonight for the first time in a couple of weeks it throws an "Out of Range" error whereas once it gave a correct result.
My test problem is basically a mortgage of PV = 153295, FV = 0, PMT = 976.25, with N = 300, NP = 12, NI = 2. The correct interest rate is around 5.95%/yr, which the program used to spit out to high accuracy. Now the solver proceeds very quickly to the error noted.
I'm baffled. I am using the latest version, and I can produce this on the real calc and the emulator.
Just thought I would share this to see if anyone else can reproduce it.
