1414213562373
1414213562373 is a 13-digit integer formed by removing the decimal point from the decimal expansion of the mathematical constant the square root of 2 and taking the first 13 digits in sequence. Since sqrt(2) = 1.414213562373095..., removing the decimal point yields the digit string 1414213562373095..., of which 1414213562373 are the initial digits. The number itself has no special mathematical value beyond being a truncation of sqrt(2)’s expansion.
Mathematically, sqrt(2) is the positive real number that satisfies x^2 = 2. It is irrational, meaning its
In practical contexts, such truncated digit strings are sometimes used in demonstrations of floating-point precision, parsing,
