Before you write

• Wrong result? Tell us which calculator, the numbers you entered, and what answer you expected. We test every tool against known examples, but we fix real bugs fast.
• New calculator idea? Tell us what it should calculate and we will consider adding it — we publish new calculators every week.
• Press or partnerships: include "Partnership" in the subject line.
