: a valid C format code. This should be of the form
indicates that up to two digits may be used to specify the field width and precision respectively. Only % and

can be one of
or # and
can be e, E, f, g or G. Thus, possible formats include %f,
, %.6e. form
is used in conjunction with argument cmplxform
, to print elements of the matrix
In addition, x04ddc
chooses its own format code when form
If , x04ddc will choose a format code such that numbers will be printed with either a %8.4f, a %11.4f or a %13.4e format. The %8.4f code is chosen if the sizes of all the matrix elements to be printed lie between and . The %11.4f code is chosen if the sizes of all the matrix elements to be printed lie between and . Otherwise the %13.4e code is chosen.
If , x04ddc will choose a format code such that numbers will be printed to as many significant digits as are necessary to distinguish between neighbouring machine numbers. Thus any two numbers that are stored with different internal representations should look different on output.
More complicated values of form
, to print a Complex number in a desired form, may be used. See the description of argument cmplxform
above for more details.
