And as a not very well scaled problem.Yes, it is the Earth's radius. What is more real than that? And very well scaled for the above mentioned calculators. All HP branded ones give fair enough answer. Apparently Hewlett Packard did something very well with their solver, which doesn't seem to happen with others. Regards RE: Announce: HP-15C Simulator / Release 3.3.00, Build 5403 - RMollov - 01-25-2014 04:19 AM You are right, Thomas.

Quote:I'm wondering if I'm doing something wrong.This happens even with these initial guesses: 0, 120. It appears the solver doesn't handle the situation properly when both guesses are on the same side of the root.

I've never noticed this until now as I use the period as radix mark.

But this inconsistency saves one keystroke per digit when editing the program file. ;-) Torsten RE: Announce: HP-15C Simulator / Release 3.3.00, Build 5403 - RMollov - 01-26-2014 10:28 AM (01-25-2014 03:29 AM)Thomas Klemm Wrote: I guess it's the solution to a rope around the earth problem:Sure it is. There are a few non-intuitive problems which I like giving to over-confident people to solve. Cheers, |
