Have a question, found a result that looks wrong, or want a calculator that is not here yet? Send a message using the form below, or email foremancalc@gmail.com. I reply within two business days.

Useful things to include when you report a result: the calculator name, the numbers you entered, and the figure you expected. That makes it quick to check and fix.
