I am writing a program for a C++ class and I need to be able to round my numbers up to the nearest 1000 (not 1000th, the actual number 1000). For example, if my variable value came back as 325, I would need a function to round it to 1000, if the variable came back as 1555, I would need to round to 2000. Any suggestions? Other than floor and ceiling functions, which do not appear to apply in my case, I cannot find any functions available in C++. I am very new to programming and I am not sure where to go from here.
Thanks!

you can use IF statements...
if ( number <= 1499 )
number = 1000;
if ( number > 1499 )
number = 2000;
...something like that

a possible algorithm is
(1) number is an int value 5678
(2) mulltiplier is an int initial value 10
(3) have a loop -
while(number > multiplier*10) multiplier *= 10;
-
(4) evaluating -
(int)(ceil( (float) number / multiplier)) * multiplier
-
gives 6000

Missing Help Files
When I enter "recordset" as the keyword and search the Visual Basic Help index,
I get many topics of interest in the resulting list. But there isn't any
information available from clicking on many of the available topics (mostly
methods but some properties are also unavailable). This same problem occurs
with many, if not most, keywords.
Is there any way I can activate these "missing" help topics? HELP!

I am working on .NET Version 2003 making an SDI application that calls MS Excel 2003.
I added a menu item called "MyApp Help" in the end of the menu bar to show Help-> About.
The application calls MS Excel, so the scenario is that I am supposed to see the Excel Menu bar,

I am able to see the menu bar, but in case of Help, I see the Help of Excel and help of my application, both as a submenu of help.
