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%.xor() method returns a new instance with the logical XOR of the lane values (a ^ b).

Syntax

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

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

SIMD.Bool8x16.xor(a, b)
SIMD.Bool16x8.xor(a, b)
SIMD.Bool32x4.xor(a, b)
SIMD.Bool64x2.xor(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 logical XOR of the lane values (a ^ b).

Description

The bitwise XOR operation yields 1, if a and b are different. The truth table for the XOR operation is:

a b a ^ b
0 0 0
0 1 1
1 0 1
1 1 0

For example, a bitwise XOR of 5 & 1 results in 0100 which is 4 in decimal.

5  0101
1  0001
   ----
4  0100

Examples

Bitwise XOR of two Int32x4

var a = SIMD.Int32x4(1, 2, 4, 8);
var b = SIMD.Int32x4(5, 5, 5, 5);
SIMD.Int32x4.xor(a, b);
// Int32x4[4, 7, 1, 13]
