Try this:

// ----------
//
// Simply "returns" a vector in a string in POV-Ray notation
//
#macro v_string (V)
  concat ("<", str (V.x, 0, 4),", ", str (V.y, 0, 4),", ", str (V.z, 0, 
4),">")
#end


#declare Wanna_see_this_vector = <2, 0.1, 12.5>;

// Should print <2, 0.1, 12.5> to the debug output
#debug v_string (Wanna_see_this_vector)
// ----------
