Description 
p 
Probability, real positive value on closed interval [0,1]. 
a 
Distribution scale parameter, real positive value. 
b 
Distribution shape parameter, real positive value, smaller than x. 
Returns

the Pareto distribution point percent function (PPF) for probability p using the parameters a and b. Probability p must lie on the interval [0,1], otherwise the result is NAN.

Description

function ParetoCDF(x, a, b: single): single; overload;
