SIMD.or

The static SIMD.%type%.or() method returns a new instance with the logical OR of the lane values (a | b). This operation exists only on integer and boolean SIMD types.

Syntax

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

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

SIMD.Bool8x16.or(a, b)
SIMD.Bool16x8.or(a, b)
SIMD.Bool32x4.or(a, b)
SIMD.Bool64x2.or(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 OR of the lane values (a | b).

Description

The bitwise OR operation yields 1, if either a or b are 1. The truth table for the OR operation is:

a	b	a | b
0	0	0
0	1	1
1	0	1
1	1	1

For example, a bitwise OR of 5 & 1 results in 0101 which is 5 in decimal.

5  0101
1  0001
   ----
5  0101

Examples

Bitwise OR of two Int32x4

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