Hi there!  I've been programming about a week in c++ and was wondering if
any of you could answer a question for me.

I want to display a dollar amount (#.##) with two numbers after the decimal
point.  My book says I can use something like
cout << setprecision(2) << number_to_display << endl;

but setprecision() works on significant digits, so 23 with setprecision(2)
shows only 23, and 1 shows as 1.0.

I have a number to display 0.096875 (the tax for something) and when I use
setprecision(1) I get "0.1" so I set it to 2, and get "0.097" ! I can't get
it to two digits.  If there is a better way please tell me.  Maybe there is
a different function I should use.  I'm pretty sure my stuff is uptodate
because I downloaded it just last week.

Thanks again for your help.
Kirk
