Considerations when using the BETA.DIST function

If any argument is nonnumeric, BETA.DIST returns the #VALUE! error value. If any argument is not an integer, it is rounded. 

If alpha ≤ 0 or beta ≤ 0, BETA.DIST returns the #NUM! error value. If x < A, x > B, or A = B, BETA.DIST returns the #NUM! error value. 

If you omit values for A and B, BETA.DIST uses the standard cumulative beta distribution, so that A = 0 and B = 1.
