Hi,

one way to achieve that could be: 
 - write the float on a string stream 
 - turn the stream into a string 

in other words something like:
  ...
  std::ostringstream oss;
  oss << the_float;
  return oss.str();
  ...

function "fmod" is used to compute the remainder of two floats,
example: fmod(7.2, 4) will yield: 3.2

Hi,

Why you dont try with:  floatnum  = atof (string_num)

If you prefer C-style, you can use sprintf(), which is a universal
solution, you can use it with any type:

--------------------------
float f = 3.14f;
char str[20];

sprintf(str, "%.2f", f);
--------------------------
