Three steps to create a new calculator
To create a new calculator you must perform three simple tasks:
- Define input and result parameters.
- Write an article using MarkDown markup.
To make your new calculator available to site visitors you can write a short article (the calculator description) using the article editor. The article may contain calculators, tables, images and other features provided by MarkDown markup language.
To perform some calculations you may need some structured data. The PLANETCALC calculators can use data in XML, JSON or HTML-table formats from external websites.
In addition you may create data table or table hierarchy using the PLANETCALC handbook editor.

The calculators can reuse the parameters and algorithms of other calculators.

Translation to foreign languages
The site user interface is translated into foreign languages. The calculators, articles and handbook can be translated into the same languages using translation editor.
A calculator developer should address future translation possibilities. Since any calculator parameter can be easily translated by the translation editor, any strings used in the calculator must be stored into special parameters (resources), instead of writing it directly in a calculator code.
