Returns the numeric product of self and other:
Example
Complex.rect(9, 8) * 4 # => (36+32i) Complex.rect(20, 9) * 9.8 # => (196.0+88.2i) Complex.rect(2, 3) * Complex.rect(2, 3) # => (-5+12i) Complex.rect(900) * Complex.rect(1) # => (900+0i) Complex.rect(-2, 9) * Complex.rect(-9, 2) # => (0-85i) Complex.rect(9, 8) * Rational(2, 3) # => ((6/1)+(16/3)*i)
