Usage REAL X,A,Y

Y=FNF_exp(A,X)

Description

FNF_exp returns the value of the probability density function of the exponential probability distribution with parameter a at x, f(x;a). F(x;a) is defined by the expression

F(x;a) is defined for positive values of a.

Errors

FNF_exp causes an HTBasic error if its arguments are not all of type REAL or if a is negative or zero.
