Note though that ABS for complex numbers can be fairly slow when
operating on large amounts of data (eg. big arrays, inner loops).
Sometimes the use of ABS in not essential if, for example, you have a
situation requiring the following:

ABS(z) GT threshold

then it is quicker to use

FLOAT(CONJ(z) * z) GT threshold^2

instead.
