Complex-base system

A complex-base system typically refers to a numerical system that uses complex numbers as its base. Most common numerical systems, like decimal (base 10) or binary (base 2), use real numbers as bases. In a complex-base system, the base can be a complex number—often represented as \( a + bi \), where \( a \) and \( b \) are real numbers, and \( i \) is the imaginary unit defined by \( i^2 = -1 \).
