The following functions are associated with the F-distribution equation:

dF(x, d1, d2)—Returns the probability density for value x.
pF(x, d1, d2)—Returns the cumulative probability distribution for value x.
qF(p, d1, d2)—Returns the inverse cumulative probability distribution for probability p.
rF(m, d1, d2)—Returns a vector of m random numbers having the F-distribution.
x is a scalar or vector of real values, x ≥ 0. To allow integration and other operations over this argument, values outside of the stated range are allowed, but they produce a 0 result.
d1, d2 are positive integers representing the degrees of freedom. While the distribution equation is meant to be formulated for integers, you can also use real values.
p is a real probability, 0 ≤ p ≤ 1.
m is an integer, m > 0.
