Better understanding numerical accuracy

Understanding how numerical accuracy impacts calculations is hard. Floating-point arithmetic is non intuitive and not easy to analyze. To help students, professors or any programer understand more about numerical accuracy Numalis provides on this page a free, online, accuracy toolkit in the form of a small analyzer.

This analyzer allows you to write programs and discover their numerical accuracy. For a presentation on how to use this toolkit please watch the video below, and for a full documentation please read the documentation page first.
Do not hesitate to use the examples provided in the toolkit. If you have any question please contact us through
