We believe in a future in which the web is a preferred environment for numerical computation. To help realize this future, we've built stdlib. stdlib is a standard library, with an emphasis on numerical and scientific computation, written in JavaScript (and C) for execution in browsers and in Node.js.

The library is fully decomposable, being architected in such a way that you can swap out and mix and match APIs and functionality to cater to your exact preferences and use cases.

When you use stdlib, you can be absolutely certain that you are using the most thorough, rigorous, well-written, studied, documented, tested, measured, and high-quality code out there.

To join us in bringing numerical computing to the web, get started by checking us out on GitHub, and please consider financially supporting stdlib. We greatly appreciate your continued support!

C APIs for registering a Node-API module exporting interfaces for invoking quinary numerical functions.

## Installation ```bash npm install @stdlib/math-base-napi-quinary ```

## Usage ```javascript var headerDir = require( '@stdlib/math-base-napi-quinary' ); ``` #### headerDir Absolute file path for the directory containing header files for C APIs. ```javascript var dir = headerDir; // returns ```

## Examples ```javascript var headerDir = require( '@stdlib/math-base-napi-quinary' ); console.log( headerDir ); // => ```

## C APIs

### Usage ```c #include "stdlib/math/base/napi/quinary.h" ``` #### STDLIB_MATH_BASE_NAPI_MODULE_DDDDD_D( fcn ) Macro for registering a Node-API module exporting an interface for invoking a quinary function accepting and returning double-precision floating-point numbers. ```c static double add( const double x, const double y, const double z, const double w, const double u ) { return x + y + z + w + u; } // ... // Register a Node-API module: STDLIB_MATH_BASE_NAPI_MODULE_DDDDD_D( add ); ``` The macro expects the following arguments: - **fcn**: `double (*fcn)( double, double, double, double, double )` quinary function. When used, this macro should be used **instead of** `NAPI_MODULE`. The macro includes `NAPI_MODULE`, thus ensuring Node-API module registration. #### stdlib_math_base_napi_ddddd_d( env, info, fcn ) Invokes a quinary function accepting and returning double-precision floating-point numbers. ```c #include // ... static double add( const double x, const double y, const double z, const double w, const double u ) { return x + y + z + w + u; } // ... /** * 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_ddddd_d( env, info, add ); } // ... ``` 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)( double, double, double, double, double )` quinary function. ```c void stdlib_math_base_napi_ddddd_d( napi_env env, napi_callback_info info, double (*fcn)( double, double, double, double, double ) ); ``` #### STDLIB_MATH_BASE_NAPI_MODULE_FFFFF_F( fcn ) Macro for registering a Node-API module exporting an interface for invoking a quinary function accepting and returning single-precision floating-point numbers. ```c static float addf( const float x, const float y, const float z, const float w, const float u ) { return x + y + z + w + u; } // ... // Register a Node-API module: STDLIB_MATH_BASE_NAPI_MODULE_FFFFF_F( addf ); ``` The macro expects the following arguments: - **fcn**: `float (*fcn)( float, float, float, float, float )` quinary function. When used, this macro should be used **instead of** `NAPI_MODULE`. The macro includes `NAPI_MODULE`, thus ensuring Node-API module registration. #### stdlib_math_base_napi_fffff_f( env, info, fcn ) Invokes a quinary function accepting and returning single-precision floating-point numbers. ```c #include // ... static float addf( const float x, const float y, const float z, const float w, const float u ) { return x + y + z + w + u; } // ... /** * 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_fffff_f( env, info, addf ); } // ... ``` 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] float (*fcn)( float, float, float, float, float )` quinary function. ```c void stdlib_math_base_napi_fffff_f( napi_env env, napi_callback_info info, float (*fcn)( float, float, float, float, float ) ); ```

### Notes - The C-API functions expect that the callback `info` argument provides access to the following JavaScript arguments: - `x`: input value. - `y`: input value. - `z`: input value. - `w`: input value. - `u`: input value.
