Exception for math.square on complex, imaginary part

Specification

Math

\[\begin{array}{l} \\ re \cdot im + im \cdot re \end{array} \]

FPCore

(FPCore im_sqr (re im) :precision binary64 (+ (* re im) (* im re)))

C

double im_sqr(double re, double im) {
	return (re * im) + (im * re);
}

Fortran

real(8) function im_sqr(re, im)
    real(8), intent (in) :: re
    real(8), intent (in) :: im
    im_sqr = (re * im) + (im * re)
end function

Java

public static double im_sqr(double re, double im) {
	return (re * im) + (im * re);
}

Python

def im_sqr(re, im):
	return (re * im) + (im * re)

Julia

function im_sqr(re, im)
	return Float64(Float64(re * im) + Float64(im * re))
end

MATLAB

function tmp = im_sqr(re, im)
	tmp = (re * im) + (im * re);
end

Wolfram

im$95$sqr[re_, im_] := N[(N[(re * im), $MachinePrecision] + N[(im * re), $MachinePrecision]), $MachinePrecision]

Reproduce
