SIMD.fromUint16x8Bits
SIMD.fromUint16x8Bits
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%.fromUint16x8Bits()方法使用Uint16x8的逐位副本创建新的SIMD数据类型。
语法
SIMD.Float64x2.fromUint16x8Bits(t)
SIMD.Float32x4.fromUint16x8Bits(t)
SIMD.Int32x4.fromUint16x8Bits(t)
SIMD.Int8x16.fromUint16x8Bits(t)
SIMD.Int16x8.fromUint16x8Bits(t)
SIMD.Uint32x4.fromUint16x8Bits(t)
SIMD.Uint8x16.fromUint16x8Bits(t)
参数
t从（按位）转换的Uint16x8 SIMD类型。
返回值
一个新的SIMD数据类型，具有Uint16x8的逐位拷贝。
例子
SIMD.Float64x2.fromUint16x8Bits
var t = SIMD.Uint16x8(0, 0, 0, 16368, 0, 0, 0, 16384
SIMD.Float64x2.fromUint16x8Bits(t
// Float64x2[1.0, 2.0]
SIMD.Float32x4.fromUint16x8Bits
var t = SIMD.Uint16x8(0, 16256, 0, 16384, 0, 16448, 0, 16512
SIMD.Float32x4.fromUint16x8Bits(t
// Float32x4[1.0, 2.0, 3.0, 4.0]
SIMD.Int32x4.fromUint16x8Bits
var t = SIMD.Uint16x8(1, 2, 3, 4, 5, 6, 7, 8
SIMD.Int32x4.fromUint16x8Bits(t
// Int32x4[131073, 262147, 393221, 524295]
SIMD.Int8x16.fromUint16x8Bits
var t = SIMD.Uint16x8(1, 2, 3, 4, 5, 6, 7, 8
SIMD.Int8x16.fromUint16x8Bits(t
// Int8x16[1,0,2,0,3,0,4,0,5,0,6,0,7,0,8,0]
