How do I round up to the next 100?

[krisbkreeme]

For example a user enters a number

double number
cout << " Please enter a number ";
cin >> number
// user enters number 1430

cout << "Your New Number is " << new_number

how do i get new_number to go to the next 100 (aka 1500)

Check the <cmath> header file--to be specific, the ceil function:

Hope it HELPS!!!
