Welcome to the HP-1 OB

Your HP-lOB rcflccls ihc superior quality and attention to detail in engineering and manufacturing that have distinguished Hewlett-Packard products for 50 years. Hewlett-Packard stands behind this calculator —we offer expertise to support its use (see inside the back cover) and world­ wide scr\icc.

Hewlett-Packard Quality

Our calculators arc made to excel and to be easy to use.

■This calculator is designed to withstand (he drops, vibrations, pollu­ tants (smog, ozone), temperature extremes, and humidity variations that it may encounter in everyday work life.

■The calculator and its manual have been designed and tested for ease of use. We added many examples to highlight (he varied uses of the calculator. Advanced materials and permanent, molded key lettering provide a long keyboard life and a positive feel to the keyboard.

■CMOS (low-power) electronics and a liquid-crystal display allow data to be retained indefinitely and the batteries to last a long time.

■The microprocessor has been optimized for fast and reliable compu­ tations using IS digits internally for precise results.

■Extensive research has created a design that has minimized the adverse effects of static electricity, a potential cause of malfunctions and data loss in calculators.

Welcome to the HP-10B

Features

The fc;iUircs of ihc HP-lOB and ihc manual reflect the needs and wishes

of many customers;

■A large 12-charactcr display.

■An At-a-Glancc section in the manual for quick reference.

■Applications to solve business and financial tasks:

■ Time Value of Money. Loans, savings, leases, and amortiza­

tion schedules.

m Interest Conversion. Nominal and effective rates.

■Cash Flows. Net present value and internal rate of return.

■Business Percentages. Percent change, markup, and margin

calculations.

■ Statistics. Mean, standard deviation, correlation cocITicicnt,

and linear regression forecasting, plus other statistical calcula­

tions.

■Enough memory to store an initial cash flow and 14 cash flow groups, with up to 99 cash flows per group.

■Fifteen numbered storage registers.

■Easy access to functions saves keystrokes and adds convenience.

■Auto-incrcmcnt capability for amortization schedules.

■Labels for amorti/;ilion and cash flows.

■Automatic constant.

■3-key memory.

■Many examples are included in the manual .so you can combine them for your specific needs.

When you turn on the HP-lOB for the first time, numbers are displayed with two decimal places and a period as the decimal point. The display format controls how many digits appear in the display.

If the result of a calculation is a number containing more significant digits than can be displayed in the current display format, the number is rounded to fit the current display setting.

Regardless of the current display format, each number is stored internally as a signed, 12-digit number with a signed, three-digit exponent.
