c++ - boost::multiprecision::float128 and C++11 -


i'm trying use boost::multiprecision::float128 (boost 1.55.0) under c++11 (gcc 4.8.1), following compiler error:

/cm/shared/apps/boost/gcc/1.55.0/include/boost/multiprecision/float128.hpp: in static member function ‘static std::numeric_limits<boost::multiprecision::number<boost::multiprecision::backends::float128_backend, et> >::number_type std::numeric_limits<boost::multiprecision::number<boost::multiprecision::backends::float128_backend, et> >::min()’: /cm/shared/apps/boost/gcc/1.55.0/include/boost/multiprecision/float128.hpp:533:55: error: unable find numeric literal operator ‘operator"" q’     static number_type (min)() boost_noexcept { return 3.36210314311209350626267781732175260e-4932q; }

can't use boost::multiprecision::float128 in c++11? or how else working?

edit

just clarify. error generated 

#include <boost/multiprecision/float128.hpp>

the compiler not happy statement

return 3.36210314311209350626267781732175260e-4932q;

in particular q confusing it. used compiler flags -std=c++11 -fabi-version=0 -march=native -mfpmath=sse

it looks known issue. try compiling -fext-numeric-literals.

javascript - Highcharts multi-color line -

Image
i looking create highchart multi-colored line. if goes down under value, become red, , when comes on value, become green . here picture example: or maybe highcharts have other charts models differentiate high or low level color? you can achieve coloring using lineargradient coloring: color: { lineargradient: { x1: 0, x2: 0, y1: 0, y2: 1 }, stops: [ [0, 'red'], [0.25, 'yellow'], [0.50, 'green'], [0.75, 'yellow'], [1, 'red'] ] } here 0 in stops relates minimum value of series , 1 maximum value, , in between percentages between values. if find percentages according values prior creating chart use correct stops values make relate specific values in data (at least approximately). see this jsfiddle example .
