I think you really want dec2hex()

A = 12;
dec2hex(A)

Read

Double Precision

and

IEEE 754

to get an understanding of what

format hex

is doing.

Specifically, on

Double Precision

They walk you through how to go from

3fd5555555555555

to 1/3. This is what MATLAB gives you (the reverse) when you do

x = 1/3;
format hex
