a mathematical constant is a special number usually a real number that is significantly interesting in some way constants arise in many areas of mathematics with constants such as e and Ï occurring in such diverse contexts as geometry number theory and calculushe constant Ï pi has a natural definition in euclidean geometry the ratio between the circumference and diameter of a circle but may be found in many places in mathematics for example the gaussian integral in complex analysis the roots of unity in number theory and cauchy distributions in probability
