Euler's constant EulerGamma is given by the limit . It appears in many integrals, and asymptotic formulas. It is sometimes known as the Euler–Mascheroni constant, and denoted .
Catalan's constant Catalan is given by the sum . It often appears in asymptotic estimates of combinatorial functions. It is variously denoted by , , or .
Khinchin's constant Khinchin (sometimes called Khintchine's constant) is given by . It gives the geometric mean of the terms in the continued fraction representation for a typical real number.
Glaisher's constant Glaisher (sometimes called the Glaisher–Kinkelin constant) satisfies , where is the Riemann zeta function. It appears in various sums and integrals, particularly those involving gamma and zeta functions.
Mathematical constants can be evaluated to arbitrary precision.
Exact computations can also be done with them.
