This is an experimental technology
Because this technology's specification has not stabilized, check the compatibility table for usage in various browsers. Also note that the syntax and behavior of an experimental technology is subject to change in future versions of browsers as the specification changes.
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]
