I am writing a program that needs the log of a value.· I have a series equation for the log that requires the value (x-1)/(x+1) to 4 or 5 decimal places.· This isn't possible within the 16-bit calculational framework.·

I also know about the **, ·*, and //·operations and suspect that I can calculate the above with 32-bit precision using these operations.· Can any one help me with the algorithms needed to calculate the log using this procedure or any other?

www.emesys.com/BS2math3.htm may help. It does not use the series approximations though.

Also, an example program to calculate dewpoint, need logarithms

Hi Tracy, is dewpoint.bsx can run with BS2?

Tracy Allen

Yes, actually the directive at the posted link is set for the BS2, not the BS2sx. It will run on any stamp.
