## ◆ nearbyint()

 Value boost::simd::nearbyint ( Value const & x )

This function object computes the rounded to even value of its parameter.

Header <boost/simd/function/nearbyint.hpp>
Notes:
• If x is $$\pm\infty$$, it is returned, unmodified
• If x is $$\pm0$$, it is returned, unmodified
• If x is NaN, NaN is returned
• to even means that half integer values are rounded to the nearest even value.
• This function is in general faster than round which do the rouding on half integer values away from zero.
