Calculates values for an F-distribution.

Syntax:

FDIST(x; r1; r2)

Degrees of freedom parameters for the F-distribution are r1 and r2, which are positive integers.

x must be greater than or equal to 0.

FDIST returns the area of the right tail of the probability density function for the F-distribution, calculating:

Example:

FDIST(1; 4; 5)

returns approximately 0.485657.
