) : float
Returns the cumulative distribution function, its inverse, or one of its parameters,
of the uniform distribution. The kind of the return value and parameters
(par1, par2, and par3)
are determined by which.
The following table lists the return value and parameters by which.
CDF, x, a, and b denotes cumulative distribution function, the value of the random variable,
the lower bound and the higher bound of the uniform distribution, respectively.
