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%.fromFloat32x4() method creates a new SIMD data type with a float conversion from a Float32x4.
Syntax
SIMD.Int32x4.fromFloat32x4(t) SIMD.Uint32x4.fromFloat32x4(t)
Parameters
t- A Float32x4 SIMD type to convert from.
Return value
A new SIMD data type with a float conversion from a Float32x4.
Exceptions
- A
RangeError, if the conversion from floating-point to integer loses precision (if the lane values are smaller than -2147483649.0 or larger than 2147483648.0)
Examples
SIMD.Int32x4.fromFloat32x4
A floating-point to integer conversion of t is performed.
var t = SIMD.Float32x4(1.0, 2.0, 3.0, 4.0); SIMD.Int32x4.fromFloat32x4(t); // Int32x4[1, 2, 3, 4] var t = SIMD.Float32x4(1.0, 2.0, 3.0, 2147483650.0); SIMD.Int32x4.fromFloat32x4(t); // RangeError: SIMD conversion loses precision
