What is DBL Epsilon?
C#'s double. Epsilon is the closest floating point number to 0. C's DBL_EPSILON is the distance between 1 and the closest floating point number greater than 1. Said another way, DBL_EPSILON is the smallest positive floating point number x such that 1 + x != 1 , often called “machine epsilon.”
