Function Documentation

operator<<()

std::ostream& operator<<	(	std::ostream &	os,
		const Vec3D &	a
	)

Adds all elements of the vector to an output stream. NB: this is a global function and a friend of the Vec3D class!

Parameters

[in]	os	the output stream,
[in]	a	The vector of interest

Returns

the output stream with vector elements added

{
    os << a.X << ' ' << a.Y << ' ' << a.Z;
    return os;
}

operator>>()

std::istream& operator>>	(	std::istream &	is,
		Vec3D &	a
	)

Reads all elements of a given vector from an input stream. NB: this is a global function and a friend of the Vec3D class!

Parameters

[in,out]	is	the input stream
[in,out]	a	the vector to be read in

Returns

the input stream from which the vector elements were read

{
    is >> a.X;
    is >> a.Y;
    is >> a.Z;
    //TW: clearing the stream avoids the nasty problem on ARM processors that the failbit is set to true if numbers below DBL_MIN=1e-308 are read.
    #if defined(__arm__) || defined(__aarch64__)
        if (is.fail()) {
            if (fabs(a.X)<std::numeric_limits<Mdouble>::min() or fabs(a.Y)<std::numeric_limits<Mdouble>::min() or fabs(a.Z)<std::numeric_limits<Mdouble>::min()) {
                logger(VERBOSE, "Read in subnormal number %", a);
                is.clear();
            }
        }
    #endif
    return is;
