`FormattedNumber`	`format(double input)` Format the given float or double to a string using the settings specified in the NumberFormatter fluent setting chain.
`FormattedNumber`	`format(Measure input)` Format the given `Measure` or `CurrencyAmount` to a string using the settings specified in the NumberFormatter fluent setting chain.
`FormattedNumber`	`format(long input)` Format the given byte, short, int, or long to a string using the settings specified in the NumberFormatter fluent setting chain.
`FormattedNumber`	`format(Number input)` Format the given `BigInteger`, `BigDecimal`, or other `Number` to a string using the settings specified in the NumberFormatter fluent setting chain.
`Format`	`toFormat()` Creates a representation of this LocalizedNumberFormat as a `Format`, enabling the use of this number formatter with APIs that need an object of that type, such as MessageFormat.

`T`	`integerWidth(IntegerWidth style)` Specifies the minimum and maximum number of digits to render before the decimal mark.
`T`	`notation(Notation notation)` Specifies the notation style (simple, scientific, or compact) for rendering numbers.
`T`	`perUnit(MeasureUnit perUnit)` Sets a unit to be used in the denominator.
`T`	`precision(Precision precision)` Specifies the rounding precision to use when formatting numbers.
`T`	`roundingMode(RoundingMode roundingMode)` Specifies how to determine the direction to round a number when it has more digits than fit in the desired precision.
`T`	`scale(Scale scale)` Sets a scale (multiplier) to be used to scale the number by an arbitrary amount before formatting.
`T`	`sign(NumberFormatter.SignDisplay style)` Sets the plus/minus sign display strategy.
`T`	`symbols(NumberingSystem ns)` Specifies that the given numbering system should be used when fetching symbols.
`T`	`symbols(DecimalFormatSymbols symbols)` Specifies the symbols (decimal separator, grouping separator, percent sign, numerals, etc.) to use when rendering numbers.
`T`	`unit(MeasureUnit unit)` Specifies the unit (unit of measure, currency, or percent) to associate with rendered numbers.

public FormattedNumber format (double input)

Format the given float or double to a string using the settings specified in the NumberFormatter fluent setting chain.

Parameters
`input`	`double`: The number to format.

Returns
`FormattedNumber`	A FormattedNumber object; call .toString() to get the string.

public FormattedNumber format (Measure input)

Format the given Measure or CurrencyAmount to a string using the settings specified in the NumberFormatter fluent setting chain.

The unit specified here overrides any unit that may have been specified in the setter chain. This method is intended for cases when each input to the number formatter has a different unit.

Parameters
`input`	`Measure`: The number to format.

Returns
`FormattedNumber`	A FormattedNumber object; call .toString() to get the string.

public FormattedNumber format (long input)

Format the given byte, short, int, or long to a string using the settings specified in the NumberFormatter fluent setting chain.

Parameters
`input`	`long`: The number to format.

Returns
`FormattedNumber`	A FormattedNumber object; call .toString() to get the string.

public FormattedNumber format (Number input)

Format the given BigInteger, BigDecimal, or other Number to a string using the settings specified in the NumberFormatter fluent setting chain.

Parameters
`input`	`Number`: The number to format.

Returns
`FormattedNumber`	A FormattedNumber object; call .toString() to get the string.

toFormat

Added in API level 30

public Format toFormat ()

Creates a representation of this LocalizedNumberFormat as a Format, enabling the use of this number formatter with APIs that need an object of that type, such as MessageFormat.

This API is not intended to be used other than for enabling API compatibility. The format(Measure) methods should normally be used when formatting numbers, not the Format object returned by this method.

Returns
`Format`	A Format wrapping this LocalizedNumberFormatter.
