NormDailyWeights: Array;
NormDailyWeights: System.Array;
The NormDailyWeights property returns normalized weights for weekdays.
The sum of normalized weights for weekdays is 7, if values of ISmCensus2.DailyWeights include at least one non-zero value.
To execute the example, add a link to the Stat system assembly.

After executing the example the console window displays normalized weights of weekdays.
The requirements and result of the Fore.NET example execution match with those in the Fore example.
