SIMD.fromFloat64x2Bits

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%.fromFloat64x2Bits() method creates a new SIMD data type with a bit-wise copy from a Float64x2.

Syntax

SIMD.Float32x4.fromFloat64x2Bits(t)

SIMD.Int32x4.fromFloat64x2Bits(t)
SIMD.Int16x8.fromFloat64x2Bits(t)
SIMD.Int8x16.fromFloat64x2Bits(t)

SIMD.Uint32x4.fromFloat64x2Bits(t)
SIMD.Uint16x8.fromFloat64x2Bits(t)
SIMD.Uint8x16.fromFloat64x2Bits(t)

Parameters

t

A Float64x2 SIMD type to convert from (bitwise).

Return value

A new SIMD data type with a bit-wise copy from a Float64x2.

Examples

SIMD.Float32x4.fromFloat64x2Bits

var t = SIMD.Float64x2(2.0, 1.875);
SIMD.Float32x4.fromFloat64x2Bits(t);
// Float32x4[0, 2.0, 0, 1.984375]

SIMD.Int32x4.fromFloat64x2Bits

var t = SIMD.Float64x2(1.0, 2.0);
SIMD.Int32x4.fromFloat64x2Bits(t);
// Int32x4[0, 1072693248, 0, 1073741824]

SIMD.Int16x8.fromFloat64x2Bits

var t = SIMD.Float64x2(1.0, 2.0);
SIMD.Int16x8.fromFloat64x2Bits(t);
// Int16x8[0, 0, 0, 16368, 0, 0, 0, 16384]

SIMD.Int8x16.fromFloat64x2Bits

var t = SIMD.Float64x2(1.0, 2.0);
SIMD.Int8x16.fromFloat64x2Bits(t);
// Int8x16[0,0,0,0,0,0,-16,63,0,0,0,0,0,0,0,64]

Specifications

SIMD is not yet part of an official standards document or draft. For standardization work and a Polyfill implementation based on typed arrays, see the ecmascript_simd GitHub repository.
