SIMD.%type%.max()

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%.max() method returns a new instance with the maximum lane values of two SIMD types (Math.max(a, b)).

Syntax

SIMD.Float32x4.max(a, b)
SIMD.Float64x2.max(a, b)

Parameters

a
An instance of a SIMD type.
b
Another instance of a SIMD type.

Return value

A new corresponding SIMD data type with the maximum lane values of a and b (Math.max(a, b)).

Description

The SIMD.%type%.max() method returns a new instance with the maximum lane values of two SIMD types (Math.max(a, b)).

This method prefers NaN over numbers. The SIMD.%type%.maxNum method prefers numbers over NaN.

Examples

var a = SIMD.Float32x4(-1, -2, 3, 5.2);
var b = SIMD.Float32x4(0, -4, 6, 5.5);
SIMD.Float32x4.max(a, b);
// Float32x4[0, -2, 6, 5.5]

var c = SIMD.Float64x2(NaN, Infinity)
var d = SIMD.Float64x2(1337, 42);
SIMD.Float64x2.max(c, d);
// Float64x2[NaN, Infinity]

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.
