[Boost-users] math round() functions: away from 0

Hello,boost/trunk/libs/math/doc/sf_and_dist/html/math_toolkit/utils/rounding/round.html says that:  Halfway cases are rounded away from zero, regardless of the current rounding direction.This is compatible with C99 TC3 and therefore the latest C++1x draft.However, when I ran this program:#include <cmath>#include <iostream>#include inline double round1(double x){    if (x >= 0.0)        return std::floor(x + 0.5);    else        return std::ceil(x - 0.5);}inline double round2(double x){    return std::floor(x + 0.5);}int main(){  std::cout.setf(std::ios_base::fixed, std::ios_base::floatfield);  std::cout.precision(1);  std::cout<< "d      floor/ceil.5        floor.5      boostmathround"<
