Detailed Description

Normal distribution function.

Given x, it returns its probability in a Gaussian normal distribution. It provides the first derivative too.


the correctness of the returned value is tested by checking it against numerical calculations. Cross-checks are also performed against the CumulativeNormalDistribution and InverseCumulativeNormal classes.
