FormattedNumber icu::number::LocalizedNumberFormatter::formatDecimal ( StringPiece  value,
UErrorCode &  status 
) const

Format the given decimal number to a string using the settings specified in the NumberFormatter fluent setting chain.

The syntax of the unformatted number is a "numeric string" as defined in the Decimal Arithmetic Specification, available at http://speleotrove.com/decimal

Parameters:
value The number to format.
status Set to an ErrorCode if one occurred in the setter chain or during formatting.
Returns:
A FormattedNumber object; call .toString() to get the string.

FormattedNumber icu::number::LocalizedNumberFormatter::formatDecimalQuantity ( const impl::DecimalQuantity &  dq,
UErrorCode &  status 
) const

Internal method.

Internal:
Do not use. This API is for internal use only.
FormattedNumber icu::number::LocalizedNumberFormatter::formatDouble ( double  value,
UErrorCode &  status 
) const

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

Parameters:
value The number to format.
status Set to an ErrorCode if one occurred in the setter chain or during formatting.
Returns:
A FormattedNumber object; call .toString() to get the string.

void icu::number::LocalizedNumberFormatter::formatImpl ( impl::UFormattedNumberData *  results,
UErrorCode &  status 
) const

This is the core entrypoint to the number formatting pipeline.

It performs self-regulation: a static code path for the first few calls, and compiling a more efficient data structure if called repeatedly.

This function is very hot, being called in every call to the number formatting pipeline.

Parameters:
results The results object. This method will mutate it to save the results.
status 
Internal:
Do not use. This API is for internal use only.
FormattedNumber icu::number::LocalizedNumberFormatter::formatInt ( int64_t  value,
UErrorCode &  status 
) const

Format the given integer number to a string using the settings specified in the NumberFormatter fluent setting chain.

Parameters:
value The number to format.
status Set to an ErrorCode if one occurred in the setter chain or during formatting.
Returns:
A FormattedNumber object; call .toString() to get the string.

void icu::number::LocalizedNumberFormatter::getAffixImpl ( bool  isPrefix,
bool  isNegative,
UnicodeString &  result,
UErrorCode &  status 
) const

Internal method for DecimalFormat compatibility.

Internal:
Do not use. This API is for internal use only.
int32_t icu::number::LocalizedNumberFormatter::getCallCount (  )  const

Internal method for testing.

Internal:
Do not use. This API is for internal use only.
const impl::NumberFormatterImpl* icu::number::LocalizedNumberFormatter::getCompiled (  )  const

Internal method for testing.

Internal:
Do not use. This API is for internal use only.
LocalizedNumberFormatter& icu::number::LocalizedNumberFormatter::operator= ( LocalizedNumberFormatter &&  src  ) 

Move assignment operator: The source LocalizedNumberFormatter will be left in a valid but undefined state.

Draft:
This API may be changed in the future versions and was introduced in ICU 62
LocalizedNumberFormatter& icu::number::LocalizedNumberFormatter::operator= ( const LocalizedNumberFormatter &  other  ) 

Copy assignment operator.

Format* icu::number::LocalizedNumberFormatter::toFormat ( UErrorCode &  status  )  const

Creates a representation of this LocalizedNumberFormat as an icu::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 formatDouble, formatInt, and formatDecimal methods should normally be used when formatting numbers, not the Format object returned by this method.

The caller owns the returned object and must delete it when finished.

Returns:
A Format wrapping this LocalizedNumberFormatter.
