FORSIG: an extension of FORTRAN with significance arithmetic
Technical Report
·
OSTI ID:6830695
We describe a new arithmetic, called significance arithmetic, and a FORTRAN-like language, called FORSIG, that account for the creation and propagation of errors in a computer program due to uncertainties in the data. To compute reasonable and accurate bounds on these errors, the dependencies developing between the variables during execution are monitored automatically and used by the significance arithmetic algorithms. These dependencies are also a measure of the sensitivity of the solution as a function of the error in the data.
