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%.mul()
method returns a new instance with the lane values negated.
Syntax
SIMD.Float32x4.neg(t) SIMD.Float64x2.neg(t) SIMD.Int8x16.neg(t) SIMD.Int16x8.neg(t) SIMD.Int32x4.neg(t) SIMD.Uint8x16.neg(t) SIMD.Uint16x8.neg(t) SIMD.Uint32x4.neg(t)
Parameters
- t
- An instance of a corresponding SIMD type.
Return value
A new corresponding SIMD data type with the lane values negated.
Examples
This example negates a Float32x4
, Float64x2
and a Int32x4
SIMD data type. Note the signed zero (-0
) in the case where a zero (0
) is negated in a float data type.
var a = SIMD.Float32x4(-1, -2, 3, 0); SIMD.Float32x4.neg(a); // Float32x4[1, 2, -3, -0] var b = SIMD.Float64x2(NaN, Infinity); SIMD.Float64x2.neg(b); // Float64x2[NaN, -Infinity] var c = SIMD.Int32x4(-1, -2, 3, 0); SIMD.Int32x4.neg(c); // Float32x4[1, 2, -3, 0]
