DoubleNumber

Generates 64bit floating point values between min and max with specified number of decimal places. Range: [minD, maxD[, if minD=1.0 and maxD=2.0 generator may produce 1.9999999999 but never 2.0, except due to rounding (e.g. with: HALF_EVEN or decimalPlaces)

Attributes
Name Description Required Min Max Allowed Values
name (Class)Name of this element. Used to identify plugin Class. Full name is required. Example: com.en.myPluginPackage.myPuginClass no 0 1
id Identification String of this element. May be used to uniquely identify a field within the children of an Element. no 0 1
Nodes
Name Description Required Min Max Allowed Values
minD Content type: Double
Minimal output value (inclusive) of this generator. Range: [minD, maxD[, if minD=1.0 and maxD=2.0 generator may produce 1.9999999999 but never 2.0, except due to rounding (e.g. with: HALF_EVEN or decimalPlaces)		 yes 1 1
format Content type: String
A format string describing how to format the number. Supported are class java.text.DecimalFormat (e.g. '#.000') and class java.util.Formatter (printf() sytle e.g.: '%.3d') syntax. If the format string contains a '%' symbol: first try to interpret format as Formatter style, with fall back to DecimalFormat. Else interpret format as DecimalFormat style with fall back to Formatter. Example: '%.3d' to format the number with 3 decimal places
Default: Unset (do not apply any special formatting to the number)		 no 0 1
distribution Distribution to be used by a generator when calculating a value no 0 1
  • bankmark.pdgf.distribution.Logarithmic
  • bankmark.pdgf.distribution.Beta
  • bankmark.pdgf.distribution.Normal
  • bankmark.pdgf.distribution.Exponential
  • bankmark.pdgf.distribution.Zeta
  • bankmark.pdgf.distribution.Binomial
maxD Content type: Double
Maximal output value (exclusive) of this generator. Range: [minD, maxD[, if minD=1.0 and maxD=2.0 generator may produce 1.9999999999 but never 2.0, except due to rounding (e.g. with: HALF_EVEN or decimalPlaces)		 yes 1 1
distinct Content type: Long
Number of distinct values (< 1 = deactivated) Note: min and max are always part of the distinct values.
Example:
<minD>1.0</minD>
<maxD>10.0</maxD>
<distinct>3</distinct>
might generate only the three distinct values 1.0, 5.0 and 10.0 as result.
Default: 0		 no 0 1
locale Content type: String
Locale to use. A locale defines the formatting rules for numbers, e.g what symbol to use as the decimal point and the thousand separator.
Examples: 'en-US', 'en-GB'. 'de-DE'
'Default is: 'us'		 no 0 1
