You can display text on the screen with sf::String (sf::Text in SFML 2.0)

I suggest you to read the tuto:
http://www.sfml-dev.org/tutorials/1.6/graphics-fonts-fr.php

To display variable like a float it's the same thing but you have to convert your number into string before.

For this he have more than one method.
You can read that : How to convert a numeric type to a string? (http://www.codeguru.com/forum/showthread.php?s=&threadid=231056)

Laurent also give an example of a converter somewhere on the forum...

[Edit] I find it :

Code: [Select]

namespace Converter
{
    template <typename T>
    std::string ToString(const T& i)
    {
        std::ostringstream stream;
        stream << i;
        return stream.str();
    }

    template <typename T>
    T FromString(const std::string& str)
    {
        std::istringstream stream(str);
        T tmp;
        stream >> tmp;
       
        return tmp;
    }
}

It's a tutorial? Looks rather like a totally random bunch of characters.
