Detailed Description
This class allows you to return a random number from a normal distribution with parameters specified in the constructor.
The probability density is based on the following:
![\[ \textrm{prob}(x) = \frac{1}{\sigma \sqrt{2 \pi} } \exp\left(-\frac{(x-\mu)^2}{2 \sigma^2}\right) \]](form_22.png)
The range is restricted to the specified [min,max] range by using rejection sampling.
