  • Method and apparatus for recovering the computing error, and a computer-readable recording medium for storing the program for executing the method
    Patent number: 6055648
    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.
