Parameters

• parameter DISPLAYLIST;

Used for enumerated (multiple-choice) attributes. Used in conjunction with the VALUELIST parameter for enumerated (multiple-choice) attributes. DISPLAYLIST, if not null, represents the display values for the attribute corresponding with the logical values listed in VALUELIST.
The display values are returned by the LogicalToDisplay method.

• parameter FORMAT;

The format specification for the data type's display value.
The value of FORMAT corresponds to the formatting option of the $FNUMBER function, which is used to perform the formatting.

• parameter MAXVAL;

The maximum allowed logical value for the data type.

• parameter MINVAL;

The minimum allowed logical value for the data type.

• parameter SCALE = 2;

The scale value (number of digits following the decimal point) for this data type. The logical value will be rounded to the specified number of decimal places.

• parameter VALUELIST;

Used for enumerated (multiple-choice) attributes. VALUELIST is either a null string ("") or a delimiter separated list (where the delimiter is the first character) of logical values. If a non-null value is present, then the attribute is restricted to values in the list, and the validation code simply checks to see if the value is in the list.

• parameter XSDTYPE = "decimal";

Declares the XSD type used when projecting XML Schemas.

Methods

• classmethod DisplayToLogical(%val As %String) as %Numeric

Converts the input value %val, which is a string representing a numeric (fixed point) value, into a logical numeric value.
Returns the value of the input string %val as a fixed point number.

• classmethod IsValid(%val As %CacheString) as %Status

Tests if the logical value %val, which is a numeric value, is valid. The validation is based on the class parameter settings used for the class attribute this data type is associated with. In this case, MAXVAL and MINVAL.

• classmethod LogicalToDisplay(%val As %Numeric) as %String

Converts the value of %val, which is in logical format, into a display string.
Returns the string value of %val.

• classmethod Normalize(%val As %CacheString) as %Numeric

Converts %val to a normalized value.

• classmethod XSDToLogical(%val As %String) as %Numeric

Converts the SOAP encoded input decimal value into a Cache %Numeric value. Returns "" for error.
