EvaluateOperator() should return NaN if operands has NaN value

According to spec [1], 'Any operation with at least one NaN argument produces NaN'

However, the compare expression results are false so possibly return the number for std::max and std::min.

e.g. ( "( param1 < param2)? param1 : param2" ) - if param1 is NaN, it will always return param2.

Therefore, check NaN existence in operands before the actual operation is consumed.
