formatting numbers on output

formatting numbers on output

[Ramesh S. Mantri]

Is formatting numbers on output possible in Ada, the way it is
permitted in other languages such as Fortran, Pascal, C and others?
Because it is displaying even small numbers in a large space. As a 
result, the output does not look too good.
Thanks in advance.

Sure.. Check out the extra parameters WIDTH, BASE, AFT, EXP, on Text_io
for Integer_io and Float_io.. They are pretty self explaining. 
AFT and EXP relate to floating point numbers and positioning of the
point. WIDTH is what you are after , this specifies the size of field
to display your small numbers in.
more complicated screen formatting becomes a little complex in ada 83 at
any rate.. usually you end up having to output vt100 or ansi codes in
your Put statement to position the cursor on the screen.
