Tests:

  • f32 iterate

     
    for (var i = 0; i < length; i++) {
      f32_b[i] = f32_a[i];
    }

  • f32 set

     
    f32_b.set(f32_a);

  • f64 iterate

     
    for (var i = 0; i < length; i++) {
      f64_b[i] = f64_a[i];
    }

  • f64 set

     
    f64_b.set(f64_a);

  • arr iterate

     
    for (var i = 0; i < length; i++) {
      arr_b[i] = arr_a[i];
    }
