WebMar 24, 2024 · A (purely) imaginary number can be written as a real number multiplied by the "imaginary unit" i (equal to the square root ), i.e., in the form . In the novel The Da Vinci Code, the character Robert Langdon jokes that character Sophie Neveu "believes in the imaginary number because it helps her break code" (Brown 2003, p. 351). WebFor a numerical quantity z, Abs [z] returns the square root of the sum of the squares of the real and imaginary parts of z. If we then square it, do we lose numerical accuracy because we are squaring after taking a square root?
