Not sure it is really operator precedence as the expression is wrapped in parenthesis. |

In certain situations, beta_q is creating a complex number (see https://stackoverflow.com/questions/66903214/why-is-python-creating-a-complex-number-here/66903343). This is because the unary - in a negative result for
(1.0 / (2.0 - rand * alpha))takes precedence over** (1.0 / (eta + 1)).This fix identifies the sign (-/+) and uses the absolute values in the calculation for beta_q, then retrospectively applies the correct sign again.
