The purpose of this package is to emulate 36 bit machine host arithmetic on a 32 bit host machine. This package will provide support for 36 bit integer, real, and double precision real numbers in the form of the standard predefined arithmetic operations. The ranges of the supported types are as follows:
Integer range of -2**35 to 2**35-1 Real range of 10**-38 to 10**38 and 0 mantissa => 27 bit binary fraction exponent => -128 to 127 Double Precision Real range of 10**-38 to 10**38 and 0 mantissa => 63 bit binary fraction exponent => -128 to 127
Any errors which occur during use of the arithmetic exception declaration in the package specification can be changed to a rename of the predefined exception "NUMERIC_ERROR" for programs needing to handle arithmetic errors in a general fashion. Conversion functions are provided to assist in programming mixed operand (32 and 36 bit) arithmetic, and to facilitate IO. These functions should be renamed if they will be used extensively so that the impact of the readability of a program's arithmetic expressions is minimized. The underlying arithmetic will be performed in twos complement arithmetic.
