Introduction

Calculator IV is just a plain old four function calculator with the folowing features:

• Arithmetic is accurate to twelve decimal digits.
• All operations are done completely with decimal numbers, no binary floating point numbers are used.
• Can be used in Algebraic or Reverse Polish Notation. RPN is not available in this version.
• Can be operated using the mouse or the keyboard.

And remember, if your calculating needs go beyond add, subtract, multiply, and divide, you might want to try out Calc-O-Matic. Available soon in most areas, check the BeWare web page or our web page for more details.
