    Dealing with decimal points

    I'm printing out a bunch of numbers with a for loop which makes up a table. Numbers such as 526.74 or 921.63 contribute to the alignment of the table since there are a total of 5 digits in the number. I also have the number 1005 being printed, but since its a whole number does not print any decimal places and ruins the alignment of that row. For example

    526.74 IS A NUMBER
    921.63 IS A NUMBER
    457.43 IS A NUMBER
    1005 IS A NUMBER

    Basically I need it to print out 1005.00 so that everything is aligned, is there anyway I can get it to print 1005.00 instead of 1005, also since its part of a for loop making any changes will effect all numbers and not just 1005.

    Thanks.

    If you want things lined up, then you should probably use some combination of the setw, setprecision and fixed stream manipulators.

    Code:
    #include <iomanip>
    
    ...
    
    std::cout << std::fixed << std::setw(7) << std::setprecision(2) << your_value_here << std::endl;

Whereas owners of cats are compelled to realize that, if you provide them with food and water and shelter and affection, they draw the conclusion that they are gods."
