SIMD.%type%.sub()
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 static SIMD.%type%.sub()
method returns a new instance with the lane values subtracted (a - b
).
Syntax
JavaScript
Copy Code
SIMD.Float32x4.sub(a, b) SIMD.Float64x2.sub(a, b) SIMD.Int8x16.sub(a, b) SIMD.Int16x8.sub(a, b) SIMD.Int32x4.sub(a, b) SIMD.Uint8x16.sub(a, b) SIMD.Uint16x8.sub(a, b) SIMD.Uint32x4.sub(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 lane values of a
and b
subtracted (a - b
).
Examples
JavaScript
Copy Code
var a = SIMD.Float32x4(-1, -2, 3, 4); var b = SIMD.Float32x4(3, 3, 3, 3); SIMD.Float32x4.sub(a, b); // Float32x4[-4, -5, 0, 1] var c = SIMD.Int16x8(1, 1, 1, 1, 1, 1, 1, 1); var d = SIMD.Int16x8(3, 3, 3, 3, 3, 3, 3, 3); SIMD.Int16x8.sub(c, d) // Int16x8[-2, -2, -2, -2, -2, -2, -2, -2]
