Calculabo

An elegant yet powerful calculator app.

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 $π$,
• Euler’s number or Napier’s constant $e$,
• Euler-Mascheroni constant or Euler’s constant $γ$,
• the golden ratio $ϕ≔(1+√5)∕2$, and
• the imaginary unit $i≔√−1$.

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