RE: Scientific RPN Calculator (with ATTINY85)
Thanks for the compliment.
Actually the ATTINY85 is an 8bit processor and (programmed with the arduinosuite) it uses 4 bytes for both the float and the double data type. So the real precision of this calculator is relatively low. There are only 6 (maybe seven) digits "trustable". Hence the SHOW function (with 7 digits) is sufficient. And as my professor said: "Calculating technical stuff with 3 reliable digits is sufficient". ;) Regards deetee
