Terms and Conditions

The answers

Arithmetic is not ownable. Copy any result here, use it anywhere, commercially or not. No
attribution is asked for.

The written content

The explanations, methods and tables are ours. Quote them with a link; do not republish pages
wholesale.

No warranty, and one specific caution

Everything here is provided as is. The calculator uses ordinary floating-point arithmetic, so
very large products and long decimals can lose precision — the tool says so when it does.
Do not rely on any figure here for financial, medical, engineering or legal purposes without
checking it. It is a reference, not an authority.

Changes

These terms may be updated. Continued use after a change means the updated terms apply.
