Float16Array - JavaScript | MDN

Constructor

Float16Array(): Creates a new Float16Array object.

Static properties

Also inherits static properties from its parent TypedArray.

Float16Array.BYTES_PER_ELEMENT: Returns a number value of the element size. 2 in the case of Float16Array.

Static methods

Inherits static methods from its parent TypedArray.

Instance properties

Also inherits instance properties from its parent TypedArray.

These properties are defined on Float16Array.prototype and shared by all Float16Array instances.

Float16Array.prototype.BYTES_PER_ELEMENT: Returns a number value of the element size. 2 in the case of a Float16Array.
Float16Array.prototype.constructor: The constructor function that created the instance object. For Float16Array instances, the initial value is the Float16Array constructor.

Instance methods

Inherits instance methods from its parent TypedArray.

Examples Different ways to create a Float16Array

// From a length
const float16 = new Float16Array(2);
float16[0] = 42;
console.log(float16[0]); // 42
console.log(float16.length); // 2
console.log(float16.BYTES_PER_ELEMENT); // 2

// From an array
const x = new Float16Array([21, 31]);
console.log(x[1]); // 31

// From another TypedArray
const y = new Float16Array(x);
console.log(y[0]); // 21

// From an ArrayBuffer
const buffer = new ArrayBuffer(32);
const z = new Float16Array(buffer, 4, 4);
console.log(z.byteOffset); // 4

// From an iterable
const iterable = (function* () {
  yield* [1, 2, 3];
})();
const float16FromIterable = new Float16Array(iterable);
console.log(float16FromIterable);
// Float16Array [1, 2, 3]
