Special Constants

Constants commonly used in fields related to Science, Mathematics, Economics. A few listed here are transcendental numbers. A transcendental number is a real or complex number that is not algebraic—that is, it is not a root of a non-zero polynomial equation with integer $($or, equivalently, rational coefficients$)$. The best-known transcendental numbers are π and e.
