Type-casting ac_float instances to ordinary floats or doubles

[AnastKap]

Hello to all,

I have an arbitrary precision floating point variable ac_float<17,2,7>, which I want to typecast in double through the following line of code:

ac_float<17,2,7> x;
double temp = (double)x;

Is there any way to do that? As far as I can see, the ac_ieee_float class has an operator for that

explicit operator double() const {
  double f;
  ac::copy_bits(d, &f);
  return f;
}

Is there any reason for which this type of operator doesn't appear in the ac_float class?
