Yes, min and max are only for reading. They tell you the minimum and maximum value the distribution may produce.

There is no way to truely generate a normal distribution who values are bound by a min and max. The best you can do is to either discard the number if outside the range, or clamp the value. For example

var r = Prob.normal(0, 1.0);

// Discard and pick another
x = r();
while (x < 1 || x > 8) {
  x = r();
}

or

var r = Prob.normal(0, 1.0);

// Clamp the value
x = r();
if (x < 1) {
  x = 1;
} else if (x > 8) {
  x = 8;
}
