[ePiX-users] integer to string conversions

[Gunnar]

I would find it very helpful if there were an easy built-in way of converting 
numbers to strings in epix.
Placing a lot of labels is preferly done by using a for-loop and 

for (x=0;x<10;x++)
    label(P(x,f(x)),"$(x,f(x)$");

doesn't give me the desired labels like (2,f(2))   (3,f(3))  etc.
Any suggestions on this? Could there perhaps be an overloaded function
std::string n2s(double x)
std::string n2s(int x)

to convert Number to String?

Best wishes
Gunnar.
