Usage                REAL X,A,B,Y
Y=FNF_cauchy(A,B,X)
 
Description                
FNF_cauchy returns the value of the probability density function of the Cauchy distribution with parameters a and b at x. This density, f(x;a,b), is defined by the expression
 
 
B must be greater than zero.
 
f(x;a,b)
 
Errors
FNF_cauchy causes an HTBasic error if its arguments are not all of type REAL or if b is negative or zero.
