Derived icu::number::NumberFormatterSettings< Derived >::adoptPerUnit | ( | icu::MeasureUnit * | perUnit | ) | const & |
Like perUnit(), but takes ownership of a pointer.
Convenient for use with the MeasureFormat factory methods that return pointers that need ownership.
Note: consider using the MeasureFormat factory methods that return by value.
perUnit | The unit to render in the denominator. |
Derived icu::number::NumberFormatterSettings< Derived >::adoptPerUnit | ( | icu::MeasureUnit * | perUnit | ) | && |

Pass this method an instance of NumberingSystem. For example, to force the locale to always use the Latin alphabet numbering system (ASCII digits):
NumberFormatter::with().adoptSymbols(NumberingSystem::createInstanceByName("latn", status))
Note: Calling this method will override any previously specified DecimalFormatSymbols or NumberingSystem.
The default is to choose the best numbering system for the locale.

The exact grouping widths will be chosen based on the locale.
Pass this method an element from the UNumberGroupingStrategy enum. For example:

This API is for internal use only.
Derived icu::number::NumberFormatterSettings< Derived >::perUnit | ( | const icu::MeasureUnit & | perUnit | ) | const & |
Sets a unit to be used in the denominator.
For example, to format "3 m/s", pass METER to the unit and SECOND to the perUnit.
Pass this method any instance of MeasureUnit. Example:
NumberFormatter::with() .unit(MeasureUnit::getMeter()) .perUnit(MeasureUnit::getSecond())
The default is not to display any unit in the denominator.
If a per-unit is specified without a primary unit via unit, the behavior is undefined.
perUnit | The unit to render in the denominator. |

Derived icu::number::NumberFormatterSettings< Derived >::precision | ( | const Precision & | precision | ) | const & |

Pass this method the return value of one of the factory methods on Precision. For example:
NumberFormatter::with().precision(Precision::fixedFraction(2))
In most cases, the default rounding strategy is to round to 6 fraction places; i.e., Precision.maxFraction(6)
. The exceptions are if compact notation is being used, then the compact notation rounding strategy is used (see Notation#compactShort for details), or if the unit is a currency, then standard currency rounding is used, which varies from currency to currency (see Precision#currency for details).
precision | The rounding precision to use. |
Derived icu::number::NumberFormatterSettings< Derived >::precision | ( | const Precision & | precision | ) | && |
Overload of precision() for use on an rvalue reference.

Sets a scale (multiplier) to be used to scale the number by an arbitrary amount before formatting.
Most common values:
Pass an element from a Scale factory method to this setter. For example:
NumberFormatter::with().scale(Scale::powerOfTen(2))
The default is to not apply any multiplier.
scale | The scale to apply when rendering numbers. |
Derived icu::number::NumberFormatterSettings< Derived >::scale | ( | const Scale & | scale | ) | && |

Specifies the symbols (decimal separator, grouping separator, percent sign, numerals, etc.) to use when rendering numbers.
Pass this method an instance of DecimalFormatSymbols. For example:
NumberFormatter::with().symbols(DecimalFormatSymbols(Locale("de_CH"), status))
Note: DecimalFormatSymbols automatically chooses the best numbering system based on the locale. In the examples above, the first three are using the Latin numbering system, and the fourth is using the Myanmar numbering system.
Note: The instance of DecimalFormatSymbols will be copied: changes made to the symbols object after passing it into the fluent chain will not be seen.
Note: Calling this method will override any previously specified DecimalFormatSymbols or NumberingSystem.
The default is to choose the symbols based on the locale specified in the fluent chain.
symbols | The DecimalFormatSymbols to use. |

symbols | The DecimalFormatSymbols to use. |
Derived icu::number::NumberFormatterSettings< Derived >::threshold | ( | int32_t | threshold | ) | const & |
Internal fluent setter to support a custom regulation threshold.
A threshold of 1 causes the data structures to be built right away. A threshold of 0 prevents the data structures from being built.
Derived icu::number::NumberFormatterSettings< Derived >::threshold | ( | int32_t | threshold | ) | && |
This API is for internal use only.
UnicodeString icu::number::NumberFormatterSettings< Derived >::toSkeleton | ( | UErrorCode & | status | ) | const |
Creates a skeleton string representation of this number formatter.
A skeleton string is a locale-agnostic serialized form of a number formatter.
Not all options are capable of being represented in the skeleton string; for example, a DecimalFormatSymbols object. If any such option is encountered, the error code is set to U_UNSUPPORTED_ERROR.
The returned skeleton is in normalized form, such that two number formatters with equivalent behavior should produce the same skeleton.
Derived icu::number::NumberFormatterSettings< Derived >::unit | ( | const icu::MeasureUnit & | unit | ) | const & |
Specifies the unit (unit of measure, currency, or percent) to associate with rendered numbers.
All units will be properly localized with locale data, and all units are compatible with notation styles, rounding precisions, and other number formatter settings.
Pass this method any instance of MeasureUnit. For units of measure:
NumberFormatter::with().unit(MeasureUnit::getMeter())
Currency:
NumberFormatter::with().unit(CurrencyUnit(u"USD", status))
Percent:
NumberFormatter::with().unit(NoUnit.percent())
See perUnit for information on how to format strings like "5 meters per second".
