Introduction
Congratulations! Whether you are new to HP calculators or an experienced
user, you will find the HP-15C a powerful and valuable calculating tool.
The HP-15C provides:
 448 bytes of program memory (one or two bytes per instruction) and
sophisticated programming capability, including conditional and
unconditional branching, subroutines, flags, and editing.
 Four advanced mathematics capabilities: complex number calculations,
matrix calculations, solving for roots, and numerical integration.
 Direct and indirect storage in up to 67 registers.
This handbook is written for you, regardless of your level of expertise.
The beginning part covers all the basic functions of the HP-15C and how to
use them. The second part covers programming and is broken down into
three subsections – The Mechanics, Examples, and Further Information – in
order to make it easy for users with varying backgrounds to find the
information they need. The last part describes the four advanced
mathematics capabilities.
Before starting these sections, you may want to gain some operating and
programming experience on the HP-15C by working through the
introductory material, The HP-15C: A Problem Solver, on page 12.
The various appendices describe additional details of calculator operation,
as well as warranty and service information. The Function Summary and
Index and the Programming Summary and Index at the back of this manual
can be used for quick reference to each function key and as a handy page
reference to more comprehensive information inside the manual.
Also available from Hewlett-Packard is the HP-15C Advanced Functions
Handbook, which provides applications and technical descriptions for the
root-solving, integration, complex number, and matrix functions.
Note: You certainly do not need to read every part of the manual
before delving into the HP-15C Advanced Functions if you are
already familiar with HP calculators. The use of _ and f
requires a knowledge of HP-15C programming.
