IDAX.PEXP - Cumulative exponential distribution

The PEXP function returns the probability that the value of a variable that follows the exponential distribution is smaller or equal to x.

Syntax

IDAX.PEXP(DOUBLE x, DOUBLE scale)

Parameter descriptions

x: Mandatory.; The value that is to be computed.; If x is negative, PEXP(x,scale) is null for all scale values.; Min: 0.00000000001; Data type: DOUBLE
scale: Mandatory.; The exponential scale.; If scale is 0 or less, PEXP(x,scale) is null for all x values.; Min: 0.00000000001; Data type: DOUBLE

Returned information

DOUBLE the cumulative probability distribution from minus infinity to point x.
