Subject: [PATCH] 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.
