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 SIMD.%type%.valueOf() method performs a type check returns the this value.
In Firefox (SpiderMonkey), this method currently always throws a TypeError as there are no proper value semantics for SIMD types defined yet.
Syntax
SIMD.Float32x4.valueOf() SIMD.Float64x2.valueOf() SIMD.Int8x16.valueOf() SIMD.Int16x8.valueOf() SIMD.Int32x4.valueOf() SIMD.Uint8x16.valueOf() SIMD.Uint16x8.valueOf() SIMD.Uint32x4.valueOf() SIMD.Bool8x16.valueOf() SIMD.Bool16x8.valueOf() SIMD.Bool32x4.valueOf() SIMD.Bool64x2.valueOf()
Return value
The this value of a SIMD object.
Exceptions
A TypeError ("can't convert SIMD value to number") is thrown when attempting to convert SIMD values to Number.
Examples
Using valueOf() with a Float32x4
var a = SIMD.Float32x4(11, 22, 33, 44); a.valueOf(); // TypeError: can't convert SIMD value to number
