SIMD.add

SIMD.js has been taken out of active development in TC39 and removed from Stage 3. It is not being pursued by web browsers for implementation anymore. SIMD operations exposed to the web are under active development within WebAssembly, with operations based on the SIMD.js operations.

The static SIMD.%type%.add() method returns a new instance with the lane values added (a + b).

Syntax

SIMD.Float32x4.add(a, b)
SIMD.Float64x2.add(a, b)

SIMD.Int8x16.add(a, b)
SIMD.Int16x8.add(a, b)
SIMD.Int32x4.add(a, b)

SIMD.Uint8x16.add(a, b) 
SIMD.Uint16x8.add(a, b) 
SIMD.Uint32x4.add(a, b)

Parameters

a
An instance of a SIMD type.
b
Another instance of a SIMD type.

Return value

A new corresponding SIMD data type with the lane values of a and b added (a + b).

Examples

var a = SIMD.Float32x4(-1, -2, 3, 4);
var b = SIMD.Float32x4(3, 3, 3, 3);
SIMD.Float32x4.add(a, b);
// Float32x4[2, 1, 6, 7]

var c = SIMD.Int16x8(1, 1, 1, 1, 1, 1, 1, 1);
var d = SIMD.Int16x8(3, 3, 3, 3, 3, 3, 3, 3);
SIMD.Int16x8.add(c, d)
// Int16x8[4, 4, 4, 4, 4, 4, 4, 4]
