Format double

[davman2002]

is there a way to format a double?
for example
Can I format 95.8586321465
as
98.96

If you're using printf, you can do:

printf("%2.2f",dblDouble) ;

and this will *guarantee* you two digit IN FRONT of the decimal and two digits BEHIND. This prints to standard output.

For using something like cout<<, you can set the parameters by using the &quot;ios::setf()&quot; function. Link:

char dblstr [50];
double y = 48538509731.957587020283475983;

strcpy (dblstr, FloatToStr .c_str ());
for (unsigned int x = 0; x < strlen (dblstr); x++)
{
if (dblstr [x] == '.')
{
x = x + 3;
dblstr [x] = NULL;
}
}

Edit1->Text = dblstr;

It could use some help for the proper rounding of the last
digit.
