Float16Array - JavaScript | MDN
Constructor
Float16Array()-
Creates a new
Float16Arrayobject.
Static properties
Also inherits static properties from its parent TypedArray.
Float16Array.BYTES_PER_ELEMENT-
Returns a number value of the element size.
2in the case ofFloat16Array.
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.
2in the case of aFloat16Array. Float16Array.prototype.constructor-
The constructor function that created the instance object. For
Float16Arrayinstances, the initial value is theFloat16Arrayconstructor.
Instance methods

Examples
Different ways to create a Float16Array
js
// 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]
