Totaling monthly budget figures
The MonthlyTotal field in the Budget form is a computed Numbers field that is formatted for Currency with two decimal places. The formula totals the values in each category to calculate the total budget.

Advertising + Entertainment + Miscellaneous + Overhead + Salaries + Travel

Subtracting, multiplying, and dividing in computed number fields
When you design a computed number field to subtract or multiply editable fields on a form, give each editable field a default value of zero.

When you design a computed number field to divide editable fields, give each editable field a default value of zero and use the following formula to perform division in the computed number field:

FIELD DivisorFieldName := DivisorFieldName;

@If(@IsNewDoc & !@IsDocBeingRecalculated; (DividendFieldName / (DivisorFieldName + 1));(DividendFieldName / DivisorFieldName))

Storing the date and time a document is created
IBM® Lotus® Notes® automatically uses internal fields to store the date and time a document is created. To display this information, define a Time field that is computed-when-displayed, and then write this formula for it:

@Created;

The field is defined as computed-when-displayed, rather than computed, to avoid storing the creation date information twice.

Determining the normal work day age of a document
This field formula determines the age of a document in work days, based on a five-day work week. In the following example:

• DateCreated is a field containing the date when the document was created. The field's data type is Date/Time, and it is computed using the formula @Created.
• Currentdate is a field containing the current date of the document. The field data type is Date/Time, and it is computed using the formula @Now. Because Notes sorts dates in seconds, you must divide by (seconds per minute) * (minutes per hour) * (hours in a day), which equals 86400.
• Weekend_days is a temporary variable that contains "Age of document in days" divided by "Number of days in a week," multiplied by "Days in a weekend."

  temp := (@Date(Currentdate) - @Date(DateCreated)) / 86400;

  weekend_days := @Integer((temp / 7)) * 2;

  wkday := @Weekday(DateCreated);

  adjust := @If(((wkday + @Modulo(temp; 7) - 7) > 0); 2; 0);

  working_days := temp - (weekend_days + adjust);

  @If(Currentdate = ""; 0; working_days);
