Built-in constants

Calculabo contains various built-in constants that are common in mathematics.

List of constants

The following five mathematical constants are included as built-in variables in Calculabo:

• pi $\pi$,
• Euler’s number or Napier’s constant $e$,
• Euler-Mascheroni constant or Euler’s constant $\gamma$,
• the golden ratio $\varphi ≔\frac{1+\sqrt{5}}{2}$, and
• the imaginary unit $i≔\sqrt{-1}$.

These constants are also visible in the Memory pane in the Calculabo interface.
