The value of 1/3 to two decimal places is 0.33 % Note that sprintf returns a string, that can be used in other % places. You can embed the format strings into a string a = sprintf( 'The value of 1/3 to two decimal places is %1.2f', n) To print with only two decimal places, consider these two examples n = 1/3 See the documentation for sprintf (doc sprintf) for much more detail. The field width is the minimum number of characters to print. A typical specifier for a decimal number is %w.df, where w is the width of the field, and d is the number of decimals, or precision. The sprintf command takes a string, with a format specifier in it, and replaces the format specifier with a numeric value. % to reset the format to the default, simply call formatīut suppose you want to print results with the correct number of significant figures, which will vary. To show more decimals, you can issue a 'format long' command format long By default, Matlab shows decimal numbers on a fixed scale with 5 decimals. A crude way to control this is through the format command. There are many times where you need to control the format of how variables are displayed in Matlab.
