EXPON.DIST function: Description, Usage, Syntax, Examples and Explanation
What is EXPON.DIST function in Excel?
Syntax of EXPON.DIST function
EXPON.DIST(x,lambda,cumulative)
The EXPON.DIST function syntax has the following arguments:
- X Required. The value of the function.
- Lambda Required. The parameter value.
- Cumulative 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.
EXPON.DIST formula explanation
- 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:
