◧ Arguments
| Argument | Type | Required | Description |
|---|---|---|---|
x |
Number | Required | The value of the function. |
lambda |
Number | Required | The parameter value. |
cumulative |
Logical | Required | A logical value that indicates which form of the exponential function to provide. If cumulative is TRUE, EXPON.DIST returns the cumulative distribution function; if FALSE, it returns the probability density function. |

Cumulative exponential distribution function
=EXPON.DIST(A2,A3,TRUE)
Result:
0.86466472
Probability exponential distribution function
=EXPON.DIST(0.2,10,FALSE)
Result:
1.35335283
§ Remarks
- If x or lambda is nonnumeric, EXPON.DIST returns the #VALUE! error value.
- If x < 0, EXPON.DIST returns the #NUM! error value.
- If lambda ≤ 0, EXPON.DIST returns the #NUM! error value.
- The equation for the probability density function is:
- The equation for the cumulative distribution function is:
✦ Tips

⚠ Common Errors
#VALUE!
If x or lambda is nonnumeric, EXPON.DIST returns the #VALUE! error value.
Fix: برای x و lambda مقدار عددی وارد کنید و مطمئن شوید سلولهای مرجع خالی یا متنی نیستند.
#NUM!
If x < 0, EXPON.DIST returns the #NUM! error value. If lambda ≤ 0, EXPON.DIST returns the #NUM! error value.
Fix: Correct the input value
