Suddenly I have started problem with simple calculations (addition and
subtraction). I have starting values in the first column wtih maximum two
significant figures. I then perform a few operations (addition and
subtraction) using numbers from a previous operation(s) for a following
operation. For instance, 1) the original value, 2.875, 2) 100-2.875, then 3)
the answer from 2) - 95.15. The final answers should be exactly 1.075, but
when I extend a number of decimal places, the value has a small value either
added or subracted from the supposed to be answers. For example, instead of
1.075, it shows 1.0750000000001200. I have tried to correct this error
without any success. Does anyone have any idea how to correct this problem?
