+# add
+
+> Compute the sum of two half-precision floating-point numbers.
+
+
+
+
+
+
+
+
+
+
+
+## Usage
+
+```javascript
+var add = require( '@stdlib/number/float16/base/add' );
+```
+
+#### add( x, y )
+
+Computes the sum of two half-precision floating-point numbers.
+
+```javascript
+var v = add( -1.0, 5.0 );
+// returns 4.0
+
+v = add( 2.0, 5.0 );
+// returns 7.0
+
+v = add( 0.0, 5.0 );
+// returns 5.0
+
+v = add( -0.0, 0.0 );
+// returns 0.0
+
+v = add( NaN, NaN );
+// returns NaN
+```
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+## Examples
+
+
+
+```javascript
+var toFloat16 = require( '@stdlib/number/float64/base/to-float16' );
+var uniform = require( '@stdlib/random/array/uniform' );
+var map = require( '@stdlib/array/base/map' );
+var logEachMap = require( '@stdlib/console/log-each-map' );
+var add = require( '@stdlib/number/float16/base/add' );
+
+var x = map( uniform( 100, -50.0, 50.0 ), toFloat16 );
+var y = map( uniform( 100, -50.0, 50.0 ), toFloat16 );
+
+logEachMap( 'add(%f, %f) => %f', x, y, add );
+```

+
+## C APIs
+
+
+
+
+
+
+
+
+
+
+
+### Usage
+
+```c
+#include "stdlib/number/float16/base/add.h"
+```
+
+#### stdlib_base_float16_add( x, y )
+
+Computes the sum of two half-precision floating-point numbers.
+
+```c
+#include "stdlib/number/float16/ctor.h"
+
+stdlib_float16_t x = stdlib_float16_from_bits( 17664 ); // => 5.0
+stdlib_float16_t y = stdlib_float16_from_bits( 16384 ); // => 2.0
+
+stdlib_float16_t v = stdlib_base_float16_add( x, y );
+```
+
+The function accepts the following arguments:
+
+- **x**: `[in] stdlib_float16_t` first input value.
+- **y**: `[in] stdlib_float16_t` second input value.
+
+```c
+stdlib_float16_t stdlib_base_float16_add( const stdlib_float16_t x, const stdlib_float16_t y );
+```
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+### Examples
