About
Every input field works as a calculator. You can use the methods and constants (case sensitive!) described on this page.
Example 1
250 * 2
Example 2
(200 - 25) * (2 / 3)
Example 3
PI * pow(10, 3) + 5 * cos(2 * PI)
Example 4
5.0125e-5 * E
The result is calculated instantly (as you type) and displayed under the input field. The message syntax will appear when the expression is not understood (or incomplete).
