Complex numbers, also referred to as imaginary numbers, are used in many fields of physics, engineering and general mathematics. These are essential to creating fast-executing, small memory-usage equations for Digital Signal Processing (DSP). The most common set of complex math is used for Fourier analysis (e.g., Fast Fourier Transform or FFT) which maps the “real” […]

]]>An automorphic number is one in which the square of the number as the same ending digits as the original number. These are also referred to as circular numbers due to their repetitive nature. For example, there are only two automorphic numbers under 100 – the numbers 25 and 76. The square of 25 is […]
