The hexadecimal display corresponds to the internal representation of the value. It is not the same as the hexadecimal notation in the C programming language.

This example illustrates the short eng and long eng formats. The value assigned to variable A increases by amultipleof10eachtime through the for loop.

A = 5.123456789;

for k=1:10 disp(A) A= A* 10;

end

The values displayed for A are shown here. The power of10 is always a multiple of 3. The value itself is expressed in 5 or more digits for the short eng format, and in exactly 15 digits for long eng:

format short eng format long eng

Algorithms If the largest element of a matrix is larger than 10³ or smaller than 10^-3, MATLAB applies a common scale factor for the short and long formats. The function format + displays +, -, and blank characters for positive, negative, and zero elements. format hex displays the hexadecimal
