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%.abs() method returns a new SIMD data type with absolute values. This operation exists only on floating point SIMD types.

Syntax

SIMD.Float32x4.abs(t)
SIMD.Float64x2.abs(t)

Parameters

t
An instance of a corresponding SIMD type.

Return value

A new corresponding SIMD data type with absolute values.

Description

The SIMD.%type%.abs method is comparable to the scalar Math.abs() function.

Examples

var a = SIMD.Float32x4(-1, -2, 0, NaN);
SIMD.Float32x4.abs(a);
// Float32x4[1, 2, 0, NaN]

var b = SIMD.Float64x2(-1, -2);
SIMD.Float64x2.abs(b);
// Float64x2[1, 2]

Browser compatibility

Experimental SIMD.js has been removed from browsers. It's still available in Firefox Nightly, but will be removed in favor of a SIMD implementation in WebAssembly. See also bug 1416723.
