mmm ....  I'm not sure because of perhaps 2.72*7.28 is converted to a float 
and then ... let see:

#include <iostream>
#include <cln/float.h>
#include <cln/float_io.h>

using namespace cln;
int main(int argc, char **argv)
{
  cl_F a,b;
  a="1.0_100";
  a=cl_float(9.0/7.0,a)*a;
  std::cout << a << std::endl;
  b="1.0_100";
  b=cl_float(9,b)/cl_float(7,b)*b;
  std::cout << b << std::endl;
}

--- The output ---
1.2857142857142858094476878250134177505970001220703125L0

Better the second, no?

Nos vemos.
