Numbers
Numbers is a calculator for Windows designed to be quick and easy to use while working on other things. It fits in a small window that can be made to stay on top while cutting and pasting between the calculator and a document, data entry screen, etc. It uses much of the familiar notation of standard equations, and it can display results as decimals or fractions, in scientific notation, in unsigned or two’s complement hexadecimal notation, or in degrees or hours, minutes and seconds.
Numbers also includes a financial calculator for solving problems involving regular payments with interest.
To use Numbers you just type the expression you want to evaluate; the result is automatically displayed. Numbers includes comprehensive Help which explains its operation and features.
