ABSTRACT:
The floating point data stored in an arbitrary cell is processed on the basis of a particular formula (S401), if an error due to column truncation occurs in a result of computation (S402) then the all the floating point data is converted to the fixed point data (S405), and the error occurring due to the floating point data is recovered automatically thereby improving the convenience of the recovery process.
