NIP. A FLOATING-POINT INTERPRETIVE PROGRAMMING SYSTEM FOR THE NAREC COMPUTER.
Abstract
An interpretive programming system has been written for the U. S. Naval Research Laboratory's medium-speed electronic digital computer (NAREC). This system, known as NIP (acronym for NAREC Interpretive Programming system), provides for automatic floating-point computation over the range between 10 to the -1233rd and +1233rd powers in either of two modes. One mode, called extended precision, allows for computational results containing as many as nineteen significant decimal digits. The other (and historically the first) mode, called regular precision, allows for as many as eleven significant decimal digits. Using the same program, it is possible to compute in either mode, which provides a basis for determining the cumulative effect of computational precision on results. This report discusses conventions and defines instructions which are available for writing a program in the NIP language. A brief description of the floating-point system, an example of a program written in extended precision, and a table of instruction execution times are included in the appendixes. (Author)
