[CLN-list] print multi-precision floating number in scientific notation

[Richard B. Kreckel]

Hi,

You should first create the desired cl_print_flags object and then pass
it as reference to the print_float function, like this:
    cl_print_flags flags;
    flags.float_readably = true;
    print_float(std::cout, flags, x[i]);

Note also that stdout is not a C++ stream. I've replaced it with cout.

  -richy.
