I don't think this change is correct, as it effectively ignores the
unsigned_integer bool. I think in the unsigned case you need to cast twice:
double -> uint32_t -> int, as in:

int temp = unsigned_integer
    ? static_cast<int>(static_cast<uint32_t>(val))
    : static_cast<int>(val);

 
     inv_op_vfp_flag_ = get_inv_op_vfp_flag(mode, val, unsigned_integer);
