+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.
