Syntax

SIMD.Float32x4.check(value)
SIMD.Float64x2.check(value)

SIMD.Int8x16.check(value)
SIMD.Int16x8.check(value)
SIMD.Int32x4.check(value)

SIMD.Uint8x16.check(value)
SIMD.Uint16x8.check(value)
SIMD.Uint32x4.check(value)

SIMD.Bool8x16.check(value) 
SIMD.Bool16x8.check(value) 
SIMD.Bool32x4.check(value)
SIMD.Bool64x2.check(value)

Parameters

value

The value to check whether it is a corresponding SIMD data type.

Return value

The corresponding SIMD data type, if valid.

Exceptions

A TypeError, if the argument is not a valid SIMD data type or does not correspond to %type%.

Examples

Checking if a SIMD data type is valid

var a = SIMD.Float32x4(1, 2, 3, 9);

SIMD.Float32x4.check(a);
// Float32x4[1, 2, 3, 9]

SIMD.Float32x4.check([1,2,3,4]);
// TypeError

SIMD.Int32x4.check(a);
// TypeError as a is a Float32x4 not an Int32x4

SIMD.Int32x4.check({});
// TypeError
SIMD.Int32x4.check('Hi Vector-Viktor!');
// TypeError
