```

#### stdlib_base_dists_exponential_median( lambda )

Returns the median of an exponential distribution.

```c
double out = stdlib_base_dists_exponential_median( 9.0 );
// returns ~0.077
```

The function accepts the following arguments:

- **lambda**: `[in] double` rate parameter.

```c
double stdlib_base_dists_exponential_median( const double lambda );
```
