SIMD.neg

The static SIMD.%type%.mul() method returns a new instance with the lane values negated.

Syntax

SIMD.Float32x4.neg(t)
SIMD.Float64x2.neg(t)

SIMD.Int8x16.neg(t)
SIMD.Int16x8.neg(t)
SIMD.Int32x4.neg(t)

SIMD.Uint8x16.neg(t) 
SIMD.Uint16x8.neg(t)
SIMD.Uint32x4.neg(t)

Parameters

t

An instance of a corresponding SIMD type.

Return value

A new corresponding SIMD data type with the lane values negated.

Examples

This example negates a Float32x4, Float64x2 and a Int32x4 SIMD data type. Note the signed zero (-0) in the case where a zero (0) is negated in a float data type.

var a = SIMD.Float32x4(-1, -2, 3, 0);
SIMD.Float32x4.neg(a);
// Float32x4[1, 2, -3, -0]

var b = SIMD.Float64x2(NaN, Infinity);
SIMD.Float64x2.neg(b);
// Float64x2[NaN, -Infinity]

var c = SIMD.Int32x4(-1, -2, 3, 0);
SIMD.Int32x4.neg(c);
// Float32x4[1, 2, -3, 0]
