Random numbers.

Hello,

If a series of Points (i.e. x and y coordinates) is generated randomly using this function:

void initPoints(){
	x = new double[nbPoints];
	y = new double[nbPoints];
	srand(2007);
	double eps = 0.000001f;

	for (int i=0; i!=nbPoints; i++){
		x[i] = (((double)rand())/RAND_MAX)*maxCoord;
		if (x[i] == maxCoord) x[i] -= eps;
		y[i] = (((double)rand())/RAND_MAX)*maxCoord;
		if (y[i] == maxCoord) y[i] -= eps;
	}
}

Does it ensure the same outcomes regardless of compiler version/settings/OS/angle between Jupiter and Uranus?

Not necessarily.

Which factors could influence it? Better yet: given that it's always run on a Windows system in MCV++2010 (but possibly a different version), can I be certain it'll be the same?

The implementation of rand(), if you can be certain that this is always the same and will never change, then it probably would have the same outcome.
