This is an experimental technology
Because this technology's specification has not stabilized, check the compatibility table for usage in various browsers. Also note that the syntax and behavior of an experimental technology is subject to change in future versions of browsers as the specification changes.
The static SIMD.%type%.fromFloat32x4Bits()
method creates a new SIMD data type with a bit-wise copy from a Float32x4.
Syntax
SIMD.Int32x4.fromFloat32x4Bits(t) SIMD.Int16x8.fromFloat32x4Bits(t) SIMD.Int8x16.fromFloat32x4Bits(t) SIMD.Uint32x4.fromFloat32x4Bits(t) SIMD.Uint16x8.fromFloat32x4Bits(t) SIMD.Uint8x16.fromFloat32x4Bits(t)
Parameters
t
- A Float32x4 SIMD type to convert from (bitwise).
Return value
A new SIMD data type with a bit-wise copy from a Float32x4.
Examples
SIMD.Int32x4.fromFloat32x4
Bits
var t = SIMD.Float32x4(1.0, 2.0, 3.0, 4.0); SIMD.Int32x4.fromFloat32x4Bits(t); // Int32x4[1065353216, 1073741824, 1077936128, 1082130432]
SIMD.Int16x8.fromFloat32x4
Bits
var t = SIMD.Float32x4(1.0, 2.0, 3.0, 4.0); SIMD.Int16x8.fromFloat32x4Bits(t); // Int16x8[0, 16256, 0, 16384, 0, 16448, 0, 16512]
SIMD.Int8x16.fromFloat32x4
Bits
var t = SIMD.Float32x4(1.0, 2.0, 3.0, 4.0); SIMD.Int8x16.fromFloat32x4Bits(t); // Int8x16[0, 0, -128, 63, 0, 0, 0, 64, 0, 0, 64, 64, 0, 0, -128, 64]
