If the largest element of a matrix is larger than 10 3 or smaller than 10 -3, MATLAB applies a common scale factor for the short and long formats. The value itself is expressed in 5 or more digits for the short eng format, and in exactly 15 digits for long eng: The power of 10 is always a multiple of 3. The values displayed for A are shown here. The value assigned to variable A increases by a multiple of 10 each time through the for loop. This example illustrates the short eng and long eng formats. It is not the same as the hexadecimal notation in the C programming language. The hexadecimal display corresponds to the internal representation of the value. Now change the format to hexadecimal, and display these same values: Set the format to its default, and display the maximum values for integers and real numbers in MATLAB: Now set format to long, and pi displays a 15-digit value while single(pi) display an 8-digit value: When the format is set to short, both pi and single(pi) display as 5-digit values: View the result for the value of pi by typing To see if compact or loose formatting is currently selected, type To see which type is currently in use, type To maintain a format across sessions, use MATLAB preferences. The specified format applies only to the current MATLAB session. Setting format to short or long does not affect the display of integer variables. For example, MATLAB uses three digits to display numbers of type int8 (i.e., -128:127). MATLAB always displays integer variables to the appropriate number of digits for the class. Computations on integer variables are done natively in integer. Contrast with compact.Д¬omputations on floating-point variables, namely single or double, are done in appropriate floating-point precision, no matter how those variables are displayed. Contrast with loose.ДЄdds linefeeds to make output more readable. Suppresses excess line feeds to show more output in a single screen. Use these format types to used to affect the spacing in the display of all variables. Hexadecimal (hexadecimal representation of a binary double-precision number) Use these format types to switch between different output display formats for all numeric variables.

The tables below show the allowable values for type, and provides an example for each type using pi. The tables shown below list the allowable values for type. For floating-point variables, for example, the default is format short (i.e., 5-digit scaled, fixed-point values).Д¬hanges the format to the specified type. The format function affects only how numbers are displayed, not how MATLAB computes or saves them.Д«y itself, changes the output format to the default appropriate for the class of the variable currently being used. Use the format function to control the output format of numeric values displayed in the Command Window. Select Preferences from the File menu in the MATLAB desktop and use Command Window preferences.
