Mathematica incorporates the latest algorithms—some original to Wolfram Research—for evaluating mathematical constants to any number of digits of precision. For basic constants like

and

, millions of digits can routinely be computed in seconds.
Degree (
°) — conversion factor from radians to degrees (entered as
Esc deg Esc)
Root — general root of a polynomial
N — evaluate to any precision
ContinuedFraction — continued fraction expansion
FullSimplify — simplify symbolic expressions involving constants
