Complex Number Class

Project: Complex Number Class

[[Complex_number|Complex numbers]] is a number that can be expressed in the form `a + bi` where `a` and `b` are real numbers and `i` represents the imaginary quantity `sqrt(-1)`. Define a complex number class that can perform multiplication, division, reciprocal, addition, subtraction, absolute value (magnitude), argument (phase), square root, exponential, and natural logarithm functions.
