floor function
math.floor the components of a vec4
@param {vec4} out the receiving vector @param {ReadonlyVec4} a vector to floor @returns {vec4} out
Implementation
List<double> floor(List<double> out, List<double> a) {
out[0] = (a[0]).floorToDouble();
out[1] = (a[1]).floorToDouble();
out[2] = (a[2]).floorToDouble();
out[3] = (a[3]).floorToDouble();
return out;
}
