Company history
Decimal began with a straightforward idea: converting a decimal to a fraction should be quick, accurate, and easy to understand. A bare result is useful, but seeing the steps makes it more useful.
That idea grew into a practical collection of conversion tools and reference pages. We continue to focus on the details that help people check their work, learn the method, and move on with confidence.
