Thus the f format is similar to the C f format. Stata’s f format is also similar to the Fortran F format, but, unlike the Fortran F format, it switches to g whenever a number is too large to be displayed in the specified f format. In addition to %w.df, the format %w.dfc can display numbers with commas.
The default format is %#s, so if a variable is str18, its default format is %18s. Stata sets poor default formats for strL variables. Stata uses %9s in all cases. Because strL variables can be so long, there is no good choice for the format; the question is merely how much of the string you want to see.
Stata uses %9s in all cases. Because strL variables can be so long, there is no good choice for the format; the question is merely how much of the string you want to see. When the format is too short for the length of the string, whether the string is str# or strL, Stata usually displays # 2 characters of the string and adds two dots at the end.
The columns are named c1 and c2 and the rows, r1, r2, and r3. These are the default names Stata comes up with when it cannot do better. The names do not play a role in the mathematics, but they are of great help when it comes to labeling the output. The names are operated on just as the numbers are. For instance, We defined B = A0A.
