SIMD.not

The static SIMD.%type%.not() method returns a new instance with the bitwise logical NOT of the lane values (~a). This operation exists only on integer and boolean SIMD types.

Syntax

SIMD.Int8x16.not(a)
SIMD.Int16x8.not(a)
SIMD.Int32x4.not(a)

SIMD.Uint8x16.not(a)
SIMD.Uint16x8.not(a)
SIMD.Uint32x4.not(a)

SIMD.Bool8x16.not(a)
SIMD.Bool16x8.not(a)
SIMD.Bool32x4.not(a)
SIMD.Bool64x2.not(a) 

Parameters

a

An instance of a SIMD type.

Return value

A new corresponding SIMD data type with the bitwise logical NOT of the lane values (~a).

Description

The bitwise NOT operation yields the inverted value (one's complement). The truth table for the NOT operation is:

a	~a
0	1
1	0

For example, a bitwise NOT of ~5 results in 1010 which is 10 in decimal.

5   0101
    ----
10  1010

Examples

Bitwise NOT of an Int32x4

var a = SIMD.Int32x4(1, 2, 4, 8);
SIMD.Int32x4.not(a);
// Int32x4[-2, -3, -5, -9]
