Matlab displays large numbers using exponential notation. However, as soon as we scale the number by larger values, we see that the formatting changes to exponential notation, to accommodate the fact that more than four digits would be needed before the decimal, or the value would require more than two leading zeros. The fprintf function behaves like its ansi c language namesake with these exceptions and extensions if you use fprintf to convert a matlab double into an integer, and the double contains a value that cannot be represented as an integer for example, it contains a fraction, matlab ignores the specified conversion and outputs the value in exponential format.
