.

You can use either of inequalities 2 - 0.0004 <= p <= 2 + 0.0004, which is the same as 1.9996 <= p <= 2.0004 or |2 - p | <= 0.0004. The plot below shows the number line and the range for p on the number line ----|=======|=======|=======|=======|=======|========|=======|=======|------ 1.9996 1.9997 1.9998 1.9999 2 2.0001 2.0002 2.0003 2.0004

=============

Keep in mind that the plot in the post by @ewatrrr is INCORRECT.
