Double Precision Decimal-to-Binary Conversion and Input

This document describes a subroutine for the PDP-8 computer that performs a double-precision decimal-to-binary conversion of numeric input from an ASR-33 Teletype.

Key features include: * Input: Accepts strings of up to eight decimal digits (signed or unsigned). * Functionality: Handles conversion to two's complement binary format, supports a 'back-arrow' for error correction, and automatically terminates on non-numeric characters. * Requirements: Requires 110 core locations and a basic PDP-8 with an ASR-33. * Usage: Loaded via PAL III or MACRO-8. It provides standard double-precision output formats compatible with other arithmetic subroutines. * Specifications: Max accepted values are 8,388,607 (signed) and 16,777,215 (unsigned).
