Please see the scenario below...am I doing something wrong or is this a gcc or multiprecision bug?
Thanks,
Rob Conde
given the following code (multiPrecisionTest.cpp):
#include
#include
typedef boost::multiprecision::int128_t int128_t;
typedef boost::multiprecision::cpp_bin_float_quad float128_t;
int main()
{
int128_t intVal;
float128_t floatVal(intVal.convert_to());
return 0;
}
--------------------------------------------------------------------------
g++ -std=c++0x -c multiPrecisionTest.cpp
I get the following error:
