Double Float Mathematical Routines

This document provides a comprehensive guide for the DBLFLT mathematical routine packages, designed for use on LINC, LINC-8, and PDP-12 computers. It covers the following programs:

• DBLFLT: The original set of double-precision floating-point mathematical routines.
• DBLFLT1: An improved version of DBLFLT that simplifies subroutine utilization and includes mnemonic symbolic entry points for easier program development.
• DBLFLT3: An expanded package built upon DBLFLT1, offering a broader range of mathematical operations, including transcendental functions (sine, cosine, log, exponent, etc.) and I/O routines.

The document details the floating-point number format (24-bit mantissa, 12-bit exponent), memory field control, argument calling sequences, halt conditions, and provides specific instructions for modifying existing programs to use these routines.
