# Float32x4.fromFloat64x2 constructor

Float32x4.fromFloat64x2(

1. Float64x2 xy

)

Creates a `Float32x4` with its x and y lanes set to values from `xy`.

The created value has Float32x4.x and Float32x4.y values which are the conversions of the Float64x2.x and Float64x2.y lanes of `xy` to 32-bit floating point values. The Float32x4.z and Float32x4.w lanes are set to the zero value.

## Implementation

    external factory Float32x4.fromFloat64x2(Float64x2 xy);
