This thesis describes a software implementation of the IEEE Floating-Point Standard (IEEE Task P754), which is believed to be an effective system for reliable, accurate computer arithmetic. The standard is implemented as a set of procedures written in Motorola 6809 assembly language. Source listings of the procedures are contained in appendices.

This is a report concerning the project I completed for my 590 (special problem) credit. The subject of this project was a system for interactive practice room scheduling by music students at NTSU. This system was created in the fall semester of 1982 as a class project for software Development (CSCI 553) with Dr. Irby. The system was not completely finished, and I received permission from Dr. Irby to finish it and help implement its use at the Music department. I was able to observe three usages of the system: Spring, Summer I, and Summer II semesters of 1983. This report details the problems encountered during each of these usages, and changes made to the system due to them. Results of a first-use survey, under documentation, and complete final code listings were also included.
