+# Float16Array Support
+
+> Detect native [`Float16Array`][mdn-float16array] support.
+
+
+
+## Usage
+
+```javascript
+var hasFloat16ArraySupport = require( '@stdlib/assert/has-float16array-support' );
+```
+
+#### hasFloat16ArraySupport()
+
+Detects if a runtime environment supports [`Float16Array`][mdn-float16array].
+
+```javascript
+var bool = hasFloat16ArraySupport();
+// returns
+```
+
+
+
+
+
+
+
+## Examples
+
+
+
+```javascript
+var hasFloat16ArraySupport = require( '@stdlib/assert/has-float16array-support' );
+
+var bool = hasFloat16ArraySupport();
+if ( bool ) {
+ console.log( 'Environment has Float16Array support.' );
