Chapter 16: Input and Output 111format optionsCommandControl the format of the output produced by disp and Octave’s normal echoingmechanism. Valid options are listed in the following table.shortlonglong eshort elong Eshort Elong gshort gOctave will try to print numbers with at least 5 significant figures withina field that is a maximum of 10 characters wide (not counting additionalspacing that is added between columns of a matrix).If Octave is unable to format a matrix so that columns line up on thedecimal point and all the numbers fit within the maximum field width, itswitches to an ‘e’ format.Octave will try to print numbers with at least 15 significant figures withina field that is a maximum of 20 characters wide (not counting additionalspacing that is added between columns of a matrix).As will the ‘short’ format, Octave will switch to an ‘e’ format if it isunable to format a matrix so that columns line up on the decimal pointand all the numbers fit within the maximum field width.The same as ‘format long’ or ‘format short’ but always display outputwith an ‘e’ format. For example, with the ‘short e’ format, pi isdisplayed as 3.14e+00.The same as ‘format long e’ or ‘format short e’ but always display outputwith an uppercase ‘E’ format. For example, with the ‘long E’ format,pi is displayed as 3.14159265358979E+00.Choose between normal ‘long’ (or ‘short’) and and ‘long e’ (or ‘shorte’) formats based on the magnitude of the number. For example, withthe ‘short g’ format, pi .^ [2; 4; 8; 16; 32] is displayed asans =3.14169.869697.4099488.59.0032e+078.1058e+15long Gshort GThe same as ‘format long g’ or ‘format short g’ but use an uppercase‘E’ format.
