4239d93dad Update multiprecision_float_test.cpp to not overflow type double. 
Previously the max value for uint1024_t could just squeeze into a double because truncation occurred during the conversion, now that cpp_int performs correctly rounded conversions, overflow occurs, and the computation fails.  Changed the problem distribution to use a multiprecision weight type, rather than double.

7561690135 Update multiprecision_int_test.cpp to not accidentality overflow type double. 
Multiprecision now performs correct rounding when converting to double - previously the max value for uint1024_t would just fit in a double if it was truncated.  But now that it's correctly rounded it overflows and breaks the calculation.
