#### stdlib_math_base_napi_id_d( env, info, fcn )

Invokes a binary function accepting a signed 32-bit integer and a double-precision floating-point number and returning a double-precision floating-point number.

```c
#include <node_api.h>
#include <stdint.h>

// ...

static double mul( const int32_t x, const double y ) {
return x * y;
}

// ...

/**
* Receives JavaScript callback invocation data.

* @param env environment under which the function is invoked
* @param info callback data
* @return Node-API value
*/
napi_value addon( napi_env env, napi_callback_info info ) {
return stdlib_math_base_napi_id_d( env, info, mul );

The function accepts the following arguments:

- **env**: `[in] napi_env` environment under which the function is invoked.
- **info**: `[in] napi_callback_info` callback data.
- **fcn**: `[in] double (*fcn)( int32_t, double )` binary function.

```c
void stdlib_math_base_napi_id_d( napi_env env, napi_callback_info info, double (*fcn)( int32_t, double ) );
```

#### stdlib_math_base_napi_ii_i( env, info, fcn )

Invokes a binary function accepting and returning signed 32-bit integers.
