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%.and()
method returns a new instance with the logical AND of the lane values (a & b
). This operation exists only on integer and boolean SIMD types.
Syntax
SIMD.Int8x16.and(a, b) SIMD.Int16x8.and(a, b) SIMD.Int32x4.and(a, b) SIMD.Uint8x16.and(a, b) SIMD.Uint16x8.and(a, b) SIMD.Uint32x4.and(a, b) SIMD.Bool8x16.and(a, b) SIMD.Bool16x8.and(a, b) SIMD.Bool32x4.and(a, b) SIMD.Bool64x2.and(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 AND of the lane values (a & b
).
Description
The bitwise AND operation only yields 1, if both a
and b
are 1. The truth table for the AND operation is:
a |
b |
a & b |
---|---|---|
0 | 0 | 0 |
0 | 1 | 0 |
1 | 0 | 0 |
1 | 1 | 1 |
For example, a bitwise AND of 5 & 1
results in 0001
which is 1 in decimal.
5 0101 1 0001 ---- 1 0001
Examples
Bitwise AND of two Int32x4
var a = SIMD.Int32x4(1, 2, 4, 8); var b = SIMD.Int32x4(5, 5, 5, 5); SIMD.Int32x4.and(a, b); // Int32x4[1, 0, 4, 0]
