  • Problem with the BA II plus

    Gens,

    I have been trying to find a way around a problem with the Ba II plus calc. apparently, there is a rounding off process in every calculation and the eventuation of all that is that I am generally off the answer by a few tens. yesterday, I was working my way through a previous SOA question paper and had two answers reading 3.7 and 3.8. To my bewilderment, The BA II spewed out 3.75. Now thats a classic catch 22.

    I am skeptical of totally relying on the authenticity of the BA II answers.Is there some way in which I can suppress this rounding off process in the BA II ????

    Thanks.

    The BA II Plus rounds internally to 9 decimal places - although it will only display what you have set it to display. You probably just need to change your number of displayed decimals as 2 is the 'default' - you can display up to 9.

      This doesn't affect how the calculator does it's internal rounding, but I think the command to show all decimal points is 2nd format 9 enter.

        i think if you go to the soa website, you could find a BA II-Plus guide. I followed the instructions and I don't get impossible numbers anymore.

          Change the format...

          Try [2nd] [FORMAT] then scroll down to 'DEC' and change it to 6 or higher by entering the number and [Enter].

          Hope that helps.

            Remember that your calculators will be reset to the default factory settings.
