§ Remarks
- If any argument is non-numeric, LOGNORMDIST returns the #VALUE! error value.
- If x ≤ 0 or if Standard_dev ≤ 0, LOGNORMDIST returns the #NUM! error value.
- The equation for the lognormal cumulative distribution function is:
✦ 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.

⚠ Common Errors
#VALUE!
If any argument is non-numeric, LOGNORMDIST returns the #VALUE! error value.
Fix: برای تمام آرگومانها مقدار عددی وارد کنید.
#NUM!
If x ≤ 0 or if Standard_dev ≤ 0, LOGNORMDIST returns the #NUM! error value.
Fix: x>0 and stdev>0
