DecimalImpUtil::ValueType32
round(ValueType32 x);Round halfway cases away from zero, regardless of the current decimal floating point rounding mode.
Special value handling: * if x is quiet NaN, quiet NaN is returned. * If x is signaling NaN, quiet NaN is returned and the value of the macro EDOM is stored into errno. * if x is +/-infinity or +/-0, it is returned unmodified.
Examples: round(0.5) ==> 1.0; round(-0.5) ==> -1.0
