ac_complex::sign_conj return value

[ajaykumarkannan]

I'm slightly confused about the definition of the sign_conj function in ac_complex. According to the PDF docs, it does the following:

sign_conj() returns (sign(real), sign(imag))) as an ac_complex<ac_int<2,true> >

However, the definition returns the following:

  ac_complex< ac_int<2,true> > sign_conj() const {
    return ac_complex< ac_int<2,true> >(
      _r ? (_r < 0 ? -1 : 1) : 0,
      _i ? (_i < 0 ? 1 : -1) : 0
    );
  }

ac_types/include/ac_complex.h

Line 212 in 1ed7f2d

ac_complex< ac_int<2,true> > sign_conj() const {

Based on the code and name, it returns the sign of the conjugate. Can someone please confirm if this is correct, and if so, perhaps update the docs, or let me know so I can send a PR to update the wording, something along the lines of:

returns (sign(real(conj())), sign(imag(conj())))) as an ac_complex<ac_int<2,true>
