Errors that occur when converting dp to px in Android

Question

I'm using this code to change dp to px.

public static int DpToPixel(Context context, int DP) {
    float px = TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, DP, context.getResources().getDisplayMetrics());
    return (int) px;
}

Problem

When creating TextView programmatically, set the width and height in pixels, as shown in the line below.

val width = DpToPixel(requireContext(), 96)
val height = DpToPixel(requireContext(), 14)

val textView = TextView(requireContext()).apply {
    layoutParams = ConstraintLayout.LayoutParams(width, height)
}

As a result, I thought that the width of textView would be 96dp and the height would be 14dp.

However, when I actually checked, the height of the textView was set to 13dp.

Qusetion

1. How can i resolve error occured when converted dp to px?

2. Is there anyway creating TextView using width and height in DP unit?

Thank you for reading my question.
