Hi,

In MATLAB, the "double" data type provides floating-point numbers with double precision, which means it can represent numbers with a high degree of accuracy. However, the display format in the MATLAB Command Window might be limiting the number of decimal places you see.

To check if the values are actually stored with higher precision, you can change the display format. MATLAB's default display format is "short", which shows up to four decimal places. You can change this to "long", which shows up to 15 decimal places for "double" precision numbers.

Here is an example MATLAB code:

format long
a = 1.123456789012345;
disp(a)

   1.123456789012345

Hope it helps.
