operator - abstract method

Complex operator -(
  1. Object subtrahend
)

Returns a Complex whose value is this - subtrahend. Uses the definitional formula

(a + bi) - (c + di) = (a-c) + (b-d)i

If either this or subtrahend has a NaN value in either part, nan is returned; otherwise infinite and NaN values are returned in the parts of the result according to the rules for double arithmetic.

Implementation
