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%.replaceLane()
method returns a new SIMD data type with the given lane value replaced.
Syntax
SIMD.Float32x4.replaceLane(t, index, value) SIMD.Float64x2.replaceLane(t, index, value) SIMD.Int8x16.replaceLane(t, index, value) SIMD.Int16x8.replaceLane(t, index, value) SIMD.Int32x4.replaceLane(t, index, value) SIMD.Uint8x16.replaceLane(t, index, value) SIMD.Uint16x8.replaceLane(t, index, value) SIMD.Uint32x4.replaceLane(t, index, value) SIMD.Bool8x16.replaceLane(t, index, value) SIMD.Bool16x8.replaceLane(t, index, value) SIMD.Bool32x4.replaceLane(t, index, value) SIMD.Bool64x2.replaceLane(t, index, value)
Parameters
t
- An instance of a corresponding SIMD type.
index
- An index number for which lane to replace.
value
- A new value to be used for the lane.
Return value
A new SIMD data type with the given lane value replaced.
Exceptions
- A
TypeError
, ift
is not the corresponding SIMD type. - A
RangeError
, if the laneindex
is out of bounds.
Examples
var t = SIMD.Float32x4(1, 2, 3, 4); SIMD.Float32x4.replaceLane(t, 2, 42); // Float32x4[1, 2, 42, 4]
