float to string? [ in c++ ]

[cassius]

I need to print my main characters health on screen. Can I just print a float or does it have to be converted to string?

DrawText only accepts strings.

 

One example on how to.

 

#include <sstream>
void draw_float( Context* c, int x, int y, float val )
{
 std::ostringstream s;
 s << val;
 c->DrawText( s.str(), x, y );
}

Thanks Roland.

Why not to use sprintf family?
