Calculation and Data Exploration Tools
Every day you log onto the Internet, you use all kinds of formulas and calculations and often without knowing it. The goal of this Web site is to offer you a way to calculate your data using some of these formulas and calculations.
All you have to do is to type in your data and optionally tag it and the tools display the resulting calculations in a datagrid. You can also plot the results in a line chart. You can sort the rows in the datagrid, adjust the display and convert your calculations to popular Web data formats; Html tables, XML, CSV and Json JavaScript objects. Included with all the tools is a demonstration data that shows how each formula or calculation works.
