Data source

The properties of a data source are:

Property Name Description
Name Specifies the name of the data source.

Data type: String

Is Default Specifies whether the data source is the default data source for the current catalog. One catalog must have one and only one default data source.

Data type: Boolean

Display Rounding Mode Specifies the rounding mode for displaying numeric data values in reports and dashboards that are created on this data source.

Data Type: Enumeration

The following are details about each rounding mode. For more information, refer to http://docs.oracle.com/javase/7/docs/api/java/math/RoundingMode.html.

  • Up
    Rounding mode to round away from zero. Always increments the digit prior to a non-zero discarded fraction.

    Example:

    Input Number Input rounded to one digit
    with Up rounding
    5.5 6
    2.5 3
    1.6 2
    1.1 2
    1.0 1
    -1.0 -1
    -1.1 -2
    -1.6 -2
    -2.5 -3
    -5.5 -6
  • Down
    Rounding mode to round towards zero. Never increments the digit prior to a discarded fraction (i.e., truncates).

    Example:

    Input Number Input rounded to one digit
    with Down rounding
    5.5 5
    2.5 2
    1.6 1
    1.1 1
    1.0 1
    -1.0 -1
    -1.1 -1
    -1.6 -1
    -2.5 -2
    -5.5 -5
  • Ceiling
    Rounding mode to round towards positive infinity. If the result is positive, behaves as for Up; if negative, behaves as for Down.

    Example:

    Input Number Input rounded to one digit
    with Ceiling rounding
    5.5 6
    2.5 3
    1.6 2
    1.1 2
    1.0 1
    -1.0 -1
    -1.1 -1
    -1.6 -1
    -2.5 -2
    -5.5 -5
  • Floor
    Rounding mode to round towards negative infinity. If the result is positive, behaves as for Down; if negative, behaves as for Up.

    Example:

    Input Number Input rounded to one digit
    with Floor rounding
    5.5 5
    2.5 2
    1.6 1
    1.1 1
    1.0 1
    -1.0 -1
    -1.1 -2
    -1.6 -2
    -2.5 -3
    -5.5 -6
  • Half up
    Rounding mode to round towards "nearest neighbor" unless both neighbors are equidistant, in which case round up. Behaves as for Up if the discarded fraction is >= 0.5; otherwise, behaves as for Down.

    Example:

    Input Number Input rounded to one digit
    with Half up rounding
    5.5 6
    2.5 3
    1.6 2
    1.1 1
    1.0 1
    -1.0 -1
    -1.1 -1
    -1.6 -2
    -2.5 -3
    -5.5 -6
  • Half down
    Rounding mode to round towards "nearest neighbor" unless both neighbors are equidistant, in which case round down. Behaves as for Up if the discarded fraction is > 0.5; otherwise, behaves as for Down.

    Example:

    Input Number Input rounded to one digit
    with Half down rounding
    5.5 5
    2.5 2
    1.6 2
    1.1 1
    1.0 1
    -1.0 -1
    -1.1 -1
    -1.6 -2
    -2.5 -2
    -5.5 -5
  • Half even
    Rounding mode to round towards the "nearest neighbor" unless both neighbors are equidistant, in which case, round towards the even neighbor. Behaves as for Half up if the digit to the left of the discarded fraction is odd; behaves as for Half down if it's even.

    Example:

    Input Number Input rounded to one digit
    with Half even rounding
    5.5 6
    2.5 2
    1.6 2
    1.1 1
    1.0 1
    -1.0 -1
    -1.1 -1
    -1.6 -2
    -2.5 -2
    -5.5 -6
