Introduction

   `ARcalc' is a program, developed for the Amiga series of computers,
that emulates a scientific calculator. `ARcalc' can be used with any
Amiga model running a version of the operating system greater then 1.3.

   Version 2.1 of the operating system introduces a localization
feature which allows programmers to write programs that are able to
comunicate with the user in the language he chooses. `ARcalc' is able
to make use of this feature, and is distributed with the files needed
to localize the calculator menu items and error messages in a number of
languages. I decided not to localize the button labels, because even on
a real calculator these are not usually localized.

   `ARcalc' provides almost every feature you might expect from a
scientific calculator, including binary, hexadecimal and octal base
calculation. The trigonometric functions can be applied to values
measured in degrees, radians, or decimal degrees; numbers can be
rappresented in scientific notation, with fixed decimal point (allowing
you to choose the number of decimal digits), or as a combination of
formats. Every computation is performed with an internal double
precision.

   The current release of `ARcalc' is version 1.1. Version 1.0 was
never released, and was not localized.

   Remember that `ARcalc' *does not* work with versions of the
operating system lower than 2.0; if you try to start it using an
earlier version of the operating system, nothing will happen.
