public class FormattedNumber
extends Object implements FormattedValue

java.lang.Object
↳	android.icu.number.FormattedNumber

The result of a number formatting operation. This class allows the result to be exported in several data types, including a String, an AttributedCharacterIterator, and a BigDecimal. Instances of this class are immutable and thread-safe.

Public methods

appendTo

Added in API level 31

public A appendTo (A appendable)

Appends the formatted string to an Appendable.

If an IOException occurs when appending to the Appendable, an unchecked ICUUncheckedIOException is thrown instead.

Parameters
`appendable`	`A`: The Appendable to which to append the string output.

Returns
`A`	The same Appendable, for chaining.

charAt

Added in API level 30

public char charAt (int index)

Returns the char value at the specified index. An index ranges from zero to length() - 1. The first char value of the sequence is at index zero, the next at index one, and so on, as for array indexing.

If the char value specified by the index is a surrogate, the surrogate value is returned.

Parameters
`index`	`int`: the index of the `char` value to be returned

Returns
`char`	the specified `char` value

getNounClass

Added in API level 35

public DisplayOptions.NounClass getNounClass ()

Gets the noun class of the formatted output. Returns UNDEFINED when the noun class is not supported yet.

Returns
`DisplayOptions.NounClass`	NounClass

getOutputUnit

Added in API level 33

public MeasureUnit getOutputUnit ()

Gets the resolved output unit.

The output unit is dependent upon the localized preferences for the usage specified via NumberFormatterSettings.usage(), and may be a unit with MeasureUnit.Complexity.MIXED unit complexity (MeasureUnit.getComplexity()), such as "foot-and-inch" or "hour-and-minute-and-second".

Returns
`MeasureUnit`	`MeasureUnit`.

length

Added in API level 30

public int length ()

Returns the length of this character sequence. The length is the number of 16-bit chars in the sequence.

Returns
`int`	the number of `char`s in this sequence

nextPosition

Added in API level 31

public boolean nextPosition (ConstrainedFieldPosition cfpos)

Iterates over field positions in the FormattedValue. This lets you determine the position of specific types of substrings, like a month or a decimal separator. To loop over all field positions:

     ConstrainedFieldPosition cfpos = new ConstrainedFieldPosition();
     while (fmtval.nextPosition(cfpos)) {
         // handle the field position; get information from cfpos
     }

Parameters
`cfpos`	`ConstrainedFieldPosition`: The object used for iteration state. This can provide constraints to iterate over only one specific field; see `ConstrainedFieldPosition#constrainField`.

Returns
`boolean`	true if a new occurrence of the field was found; false otherwise.

subSequence

Added in API level 30

public CharSequence subSequence (int start, 
                int end)

Returns a CharSequence that is a subsequence of this sequence. The subsequence starts with the char value at the specified index and ends with the char value at index end - 1. The length (in chars) of the returned sequence is end - start, so if start == end then an empty sequence is returned.

Parameters
`start`	`int`: the start index, inclusive
`end`	`int`: the end index, exclusive

Returns
`CharSequence`	the specified subsequence

toBigDecimal

Added in API level 30

public BigDecimal toBigDecimal ()

Export the formatted number as a BigDecimal. This endpoint is useful for obtaining the exact number being printed after scaling and rounding have been applied by the number formatting pipeline.

Returns
`BigDecimal`	A BigDecimal representation of the formatted number.

NumberFormatter

toCharacterIterator

Added in API level 30

public AttributedCharacterIterator toCharacterIterator ()

Exports the formatted number as an AttributedCharacterIterator.

Consider using nextPosition(ConstrainedFieldPosition) if you are trying to get field information.

Returns
`AttributedCharacterIterator`	An AttributedCharacterIterator containing full field information.

toString

Added in API level 30

public String toString ()

Returns a string representation of the object.

Returns
`String`	a string representation of the object.
