Calculator + is an advanced, extensible calculator accepting natural (infix) formula notation. There are many built in functions and operators for common scientific and binary tasks. You can easily extend Calculator + with your own functions sets, or download predefined function sets from our website for business, science and astronomy for FREE!
Calculator + always opens a standard calculator window - however, you may open as many calculator windows as you like and save them as documents.
Calculator + also provides a history log that allows you to check and modify your input or just jump to any desired calculation from the log.
Calculator + also runs as a service, so you can just type a formula in nearly any Mac app, select it and run Calculator + from the Services Menu to compute the result.
