Detailed Description

The Library.Double data type class represents a IEEE double-precision (64-bit) floating point number.

The logical value of the Double data type is a IEEE floating point value.

Member Function Documentation

DisplayToLogical()

_.Library.Double DisplayToLogical (   _, _.Library.String  val  )

static

Converts the input value val, which is a string representing a floating point value,.

into a logical floating point value.

Returns the logical floating point value of the input string val.

IsValid()

_.Library.Status IsValid (   _, _.Library.RawString  val  )

static

Tests if the logical value val, which is a floating point 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.

Reimplemented from DataType.

JSONToLogical()

_.Library.Double JSONToLogical (   _, _.Library.String  val  )

static

Converts the JSON input decimal value into a Objectscript IEEE floating point value.

Returns "" for error.

LogicalToDisplay()

_.Library.String LogicalToDisplay (   _, _.Library.Double  val  )

static

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

The formatting is based on the value of the FORMAT parameter.

Returns the formatted value of val.

LogicalToJSON()

_.Library.String LogicalToJSON (   _, _.Library.Double  val  )

static

Converts the Objectscript IEEE floating point value to the JSON double value.

In particular, the values NaN, -INF and +INF are used with that case.

LogicalToXSD()

_.Library.String LogicalToXSD (   _, _.Library.Double  val  )

static

Converts the ObjectScript IEEE floating point value to the canonical SOAP encoded double value.

In particular, the values NaN, -INF and +INF are used with that case.

XSDToLogical()

_.Library.Double XSDToLogical (   _, _.Library.String  val  )

static

Converts the SOAP encoded input decimal value into an ObjectScript IEEE floating point value.

Returns "" for error.

Member Data Documentation

DISPLAYLIST

DISPLAYLIST = None

static

The Library.Double data type class represents a IEEE double-precision (64-bit) floating point number.

The logical value of the Double data type is a IEEE floating point value.

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.

FORMAT

FORMAT = None

static

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.

SCALE

SCALE = None

static

The scale value (number of digits following the decimal point) for this data type.

This parameter only affects the display value which will be rounded to the specified number of decimal places.

VALUELIST

VALUELIST = None

static

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.
