Format a decimal number.

The number is a DecimalQuantity wrapper onto a floating point decimal number. The default implementation inNumberFormat converts the decimal number to a double and formats that.

Parameters

number	The number, a DecimalQuantity format Decimal Floating Point.
appendTo	Output parameter to receive result. Result is appended to existing contents.
pos	On input: an alignment field, if desired. On output: the offsets of the alignment field.
status	Output param filled with success/failure status.

Returns

Reference to 'appendTo' parameter.

ICU 4.4

Returns a unique class ID POLYMORPHICALLY.

Pure virtual override. This method is to implement a simple version of RTTI, since not all C++ compilers support genuine RTTI. Polymorphicoperator==() andclone() methods call this method.

Returns

The class ID for this object. All objects of a given class have the same class ID. Objects of other classes have different class IDs.

Stable:

ICU 51

Implementsicu::NumberFormat.

Return the class ID for this class.

This is useful only for comparing to a return value fromgetDynamicClassID(). For example:

.      Base* polymorphic_pointer = createPolymorphicObject();.      if (polymorphic_pointer->getDynamicClassID() ==.          Derived::getStaticClassID()) ...

Returns

The class ID for all objects of this class.

Parameters

rhs	theDecimalFormat object to be copied.

Stable:

ICU 51

Implementsicu::NumberFormat.

CompactDecimalFormat does not support parsing.

This implementation sets status to U_UNSUPPORTED_ERROR

Parameters

text	Unused.
result	Does not change.
status	Always set to U_UNSUPPORTED_ERROR.

Stable:

ICU 51

Reimplemented fromicu::NumberFormat.

Parses text from the given string as a currency amount.

Unlike theparse() method, this method will attempt to parse a generic currency name, searching for a match of this object's locale's currency display names, or for a 3-letter ISO currency code. This method will fail if this format is not a currency format, that is, if it does not contain the currency pattern symbol (U+00A4) in its prefix or suffix. This implementation always returns nullptr.

Parameters

text	the string to parse
pos	input-output position; on input, the position within text to match; must have 0 <= pos.getIndex() < text.length(); on output, the position after the last matched character. If the parse fails, the position in unchanged upon output.

Returns

if parse succeeds, a pointer to a newly-createdCurrencyAmount object (owned by the caller) containing information about the parsed currency; if parse fails, this is nullptr.
