§ Remarks
- If any argument is nonnumeric, BETAINV returns the #VALUE! error value.
- If alpha ≤ 0 or beta ≤ 0, BETAINV returns the #NUM! error value.
- If probability ≤ 0 or probability > 1, BETAINV returns the #NUM! error value.
- If you omit values for A and B, BETAINV uses the standard cumulative beta distribution, so that A = 0 and B = 1.
- Given a value for probability, BETAINV seeks that value x such that BETADIST(x, alpha, beta, A, B) = probability. Thus, precision of BETAINV depends on precision of BETADIST.
✦ Tips
- This function has been replaced with one or more new functions that may provide improved accuracy and whose names better reflect their usage. Although this function is still available for backward compatibility, you should consider using the new functions from now on, because this function may not be available in future versions of Excel.
- If you omit values for A and B, BETAINV uses the standard cumulative beta distribution, so that A = 0 and B = 1.

⚠ Common Errors
#VALUE!
If any argument is nonnumeric, BETAINV returns the #VALUE! error value.
Fix: همه آرگومانها را بررسی کنید و مطمئن شوید عدد هستند؛ موارد متنی را به عدد تبدیل کنید.
#NUM!
If alpha ≤ 0 or beta ≤ 0, BETAINV returns the #NUM! error value. If probability ≤ 0 or probability > 1, BETAINV returns the #NUM! error value.
Fix: Correct the inputs
