                            Hi there,

     Have you ever been irritated because of having a computer and
still having to use a calculator to perform some simple
calculations? 
Do you need to do some calculations every once in a while, when you
write a document using your word processor, or when you enter data
into your spreadsheet?
If your answer is yes to any of these questions then you might want
to purchase CALCULATOR.
CALCULATOR is a memory resident program which allows you to perform
calculations even if you are in the middle of editing session.
You simply press <Alt> and <Shift> keys simultaneously and the
calculator pops up on your screen. After you are done with the
calculations you simply press <Esc> and you are back in your word
processor, spreadsheet or whatever program you were in before using
CALCULATOR.
CALCULATOR has the following functions :
- additions, subtraction, multiplication, division
- inverse (1/x)
- negation
- sin, cos, tan
- Celsius - Fahrenheit conversion
- decimal and natural logarithm
- exponent of E
- x to the power of y
- pi value
- factorial
- square, and square root
- 3 modes of display : decimal, binary, and hexadecimal
- parentheses
- 10 memory cells
- on-line help
