I have been having problems with incorrect calculation of column totals when
using the SUM function. The data I have entered in the column to 20 decimal
places are as follows: 7.4, 10,14.7 and -32. These should total 0.1 but
excel calculates the total as 0.09999999999999430000

I am using Excel97 does anyone else have similar problems and does this also
occur with later versions of Excel.

Thank you.
