### Usage
176+
177+
```c
178+
#include "stdlib/stats/base/dists/poisson/quantile.h"
179+
```
180+
181+
#### stdlib_base_dists_poisson_quantile( p, lambda )
182+
183+
Evaluates the quantile function for a Poisson distribution with mean parameter `lambda` at a probability `p`.
184+
185+
```c
186+
double out = stdlib_base_dists_poisson_quantile( 0.5, 2.0 );
187+
// returns 2
188+
```
189+
190+
The function accepts the following arguments:
191+
192+
- **p**: `[in] double` input value.
193+
- **lambda**: `[in] double` mean parameter.
194+
195+
```c
196+
double stdlib_base_dists_poisson_quantile( const double p, const double lambda );
197+
```
