Function pexp

pexp<T extends Vectorizable>(
q: T,
options?: ExponentialParams & TailOptions,
): VectorResult<T>
Distribution function of the exponential distribution. Equivalent to R's pexp(q, rate = 1, lower.tail = TRUE, log.p = FALSE).
Type Parameters
- T extends Vectorizable
Parameters
- q: T
  Quantile(s): a number, number[] or Float64Array. The result has the same shape.
- options: ExponentialParams & TailOptions = {}
  rate (see ExponentialParams), lowerTail and logP (see TailOptions).
Returns VectorResult<T>
The probability (or log probability).
Example
```
pexp(1);                                  // 0.6321205588285577
pexp(1, { rate: 2, lowerTail: false });   // 0.1353352832366127
```
