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%.extractLane() method returns the value of a given lane.
Syntax
SIMD.Float32x4.extractLane(t, index) SIMD.Float64x2.extractLane(t, index) SIMD.Int8x16.extractLane(t, index) SIMD.Int16x8.extractLane(t, index) SIMD.Int32x4.extractLane(t, index) SIMD.Uint8x16.extractLane(t, index) SIMD.Uint16x8.extractLane(t, index) SIMD.Uint32x4.extractLane(t, index) SIMD.Bool8x16.extractLane(t, index) SIMD.Bool16x8.extractLane(t, index) SIMD.Bool32x4.extractLane(t, index) SIMD.Bool64x2.extractLane(t, index)
Parameters
- t
- An instance of a corresponding SIMD type.
- index
- An index number for which lane to extract. Lanes are numbered starting at 0.
Return value
The value of the extracted lane.
Exceptions
- A
TypeError, iftis not the corresponding SIMD type. - A
RangeError, if the laneindexis out of bounds.
Examples
var t = SIMD.Float32x4(1, 2, 3, 4); SIMD.Float32x4.extractLane(t, 2); // 3
