About EulerCalc

EulerCalc is an online calculator site designed to be the global reference for free, accurate, and fast calculation tools.

The name pays homage to Leonhard Euler (1707–1783), the most prolific mathematician in history and creator of much of modern mathematical notation, including the constant e, function notation f(x), and the number i.
