Returns the cumulative distribution function, its inverse, or one of its parameters,
of the normal distribution. The kind of the return value and parameters
(<parameter>par1</parameter>, <parameter>par2</parameter>, and <parameter>par3</parameter>)
are determined by <parameter>which</parameter>.
</para>
<para>
The following table lists the return value and parameters by <parameter>which</parameter>.
CDF, x, mu, and sigma denotes cumulative distribution function, the value of the random
variable, the mean and the standard deviation of the normal distribution, respectively.
