Nature of problem:
Calculation of square roots of arbitrary rational numbers using multiple-word number precision.
Modified Newton-Raphson and Gauss algorithms are used.
The accuracy of representation is adjustable.
The program is written as Assembly language subroutines with a Fortran driver.
Depending on the length of word block (precision specified). Typically for five words 90 ms and for ten words 300ms.
