SIMD.fromInt16x8Bits
SIMD.js已经从TC39中取消了积极的开发，并从第三阶段中删除了。它不再被网页浏览器所追求。暴露在 web 上的SIMD 操作在 WebAssembly 中正处于积极的发展之中, 其操作基于 SIMD. js 操作。
静态SIMD.%type%.fromInt16x8Bits()方法使用int16x8中的按位副本创建新的SIMD数据类型。
语法
SIMD.Float64x2.fromInt16x8Bits(t)
SIMD.Float32x4.fromInt16x8Bits(t)
SIMD.Int32x4.fromInt16x8Bits(t)
SIMD.Int8x16.fromInt16x8Bits(t)
SIMD.Uint32x4.fromInt16x8Bits(t)
SIMD.Uint8x16.fromInt16x8Bits(t)
SIMD.Uint16x8.fromInt16x8Bits(t)参数
t一个Int16x8 SIMD类型从（按位）转换。
返回值
一个新的SIMD数据类型，来自Int16x8的按位拷贝。
例子
SIMD.Float64x2.fromInt16x8Bits
var t = SIMD.Int16x8(0, 0, 0, 16368, 0, 0, 0, 16384);
SIMD.Float64x2.fromInt16x8Bits(t);
// Float64x2[1.0, 2.0]SIMD.Float32x4.fromInt16x8Bits
var t = SIMD.Int16x8(0, 16256, 0, 16384, 0, 16448, 0, 16512);
SIMD.Float32x4.fromInt16x8Bits(t);
// Float32x4[1.0, 2.0, 3.0, 4.0]SIMD.Int32x4.fromInt16x8Bits
var t = SIMD.Int16x8(1, 2, 3, 4, 5, 6, 7, 8);
SIMD.Int32x4.fromInt16x8Bits(t);
// Int32x4[131073, 262147, 393221, 524295]SIMD.Int8x16.fromInt16x8Bits
var t = SIMD.Int16x8(1, 2, 3, 4, 5, 6, 7, 8);
SIMD.Int8x16.fromInt16x8Bits(t);
// Int8x16[1,0,2,0,3,0,4,0,5,0,6,0,7,0,8,0]规范
