FNP_cauchyreturns the value of the integral of the Cauchy probability density function with parametersaandbatx. This integral,P(x;a,b), is defined by the expression
which reduces to
Bmust be greater than zero.
P(x;0,b)
Errors
FNP_cauchycauses an HTBasic error if its arguments are not all of type REAL or ifbis negative or zero.
