# Number of Bytes > Size (in bytes) of a [half-precision floating-point number][ieee754].

## Usage ```javascript var FLOAT16_NUM_BYTES = require( '@stdlib/constants/float16/num-bytes' ); ``` #### FLOAT16_NUM_BYTES Size (in bytes) of a [half-precision floating-point number][ieee754]. ```javascript var bool = ( FLOAT16_NUM_BYTES === 2 ); // returns true ```

## Examples ```javascript var FLOAT16_NUM_BYTES = require( '@stdlib/constants/float16/num-bytes' ); console.log( FLOAT16_NUM_BYTES ); // => 2 ```
