format rat uses a continued fraction algorithm to approximate floating-point values by ratios of small integers. format hex displays the hexadecimal representation of a binary double-precision number. The function format + displays +, -, and blank characters for positive, negative, and zero elements. format For floating-point variables, for example, the default is format short(i.e., 5-digit scaled, fixed-point values). Note The formatfunction affects only how numbers are displayed, not how MATLAB computes or saves them. 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. Description Use the formatfunction to control the output format of numeric values displayed in the Command Window. View the result for the value of pi by typing If you want to change how the variables are displayed in the variable editor, have a look at this page of the documentation. More details about the format function in the documentation.
Hexadecimal (hexadecimal representation of a binary double-precision number)Īdds linefeeds to make output more readable. 2 Answers Sorted by: 5 Use format bank to get 2 decimal displayed. Suppresses excess line feeds to show more output in a single screen. To see the current type file, use get(0,'Format'), or for compact versus loose, use get(0,'FormatSpacing'). The table below describes the allowable values for type and provides an example for pi, unless otherwise noted. BankText cur2str (Value,Digits) returns the given value in bank format. To maintain a format across sessions, instead use MATLAB preferences.īy itself, changes the output format to the default type, short, which is 5-digit scaled, fixed-point values.Ĭhanges the format to the specified type. The specified format applies only to the current session. The format function affects only how numbers are displayed, not how MATLAB computes or saves them.
Use the format function to control the output format of the numeric values displayed in the Command Window. If that's not the case for you, then you've found a bug. MATLAB performs all computations in double precision. If you set format bank and display your cell array at the command line (with e.g celldisp) then numbers will indeed show with 2 decimals. Select Preferences from the File menu in the MATLAB desktop and use Command Window preferences. Format (MATLAB Functions) MATLAB Function ReferenceĪs an alternative to format, use preferences.
