Variable Precision and Interval Arithmetic: Portable Enhancements to Fortran.

Abstract

It was the intent of the research reported here to develop, using preprocessing techniques, extensions to FORTRAN which would include: (1) the extended data types VPINTEGER, VPREAL, VPCOMPLEX and VPINTERVAL. The data types are analogous to those of standard FORTRAN and the single precision interval data type, but can be of arbitrary precision, (2) The standard built-in functions (SIN, COS, SQRT, etc.) for use with the new data types, and (3) The input/output facilities of standard FORTRAN extended for use with the extended data types.
