[in]	text_length	The length of text, or -1 if NULL-terminated.
[in,out]	parse_pos	A pointer to an offset index into text at which to begin parsing. On output, parse_pos will point after the last parsed character. This parameter may be NULL, in which case parsing begins at offset 0. If not NULL, on output the offset at which parsing ended.
[out]	currency	A pointer to the buffer to receive the parsed NULL- terminated currency. This buffer must have a capacity of at least 4 i18n_uchar characters.

Returns:

The parsed double

Exceptions:

I18N_ERROR_NONE	Successful
I18N_ERROR_INVALID_PARAMETER	Invalid function parameter

Parses a string into an int64 using an i18n_unumber_format_h.

The string will be parsed according to the i18n_unumber_format_h's locale.

Remarks:

The specific error code can be obtained using the get_last_result() method. Error codes are described in Exceptions section and i18n_error_code_e description.

Since :

2.3.1

Parameters:

[in]	fmt	The formatter to use.
[in]	text	The text to parse.
[in]	text_length	The length of text, or -1 if NULL-terminated.
[in,out]	parse_pos	If not NULL, on input a pointer to an integer specifying the offset at which to begin parsing. If not NULL, on output the offset at which parsing ended.

Returns:

The value of the parsed integer

Exceptions:

I18N_ERROR_NONE	Successful
I18N_ERROR_INVALID_PARAMETER	Invalid function parameter

Sets a numeric attribute associated with an i18n_unumber_format_h.

An example of a numeric attribute is the number of integer digits a formatter will produce. If the formatter does not understand the attribute, the call is ignored. Rule-based formatters only understand the lenient-parse attribute. The I18N_UNUMBER_ROUNDING_INCREMENT attribute is not supported.

Note that the value for the I18N_UNUMBER_PADDING_POSITION attribute should be one of the i18n_unumber_pad_position_e enumeration values.

Remarks:

Error codes are described in i18n_error_code_e description.

Since :

2.3.1

Parameters:

[in]	fmt	The formatter to set.
[in]	attr	The attribute to query; one of I18N_UNUMBER_PARSE_INT_ONLY, I18N_UNUMBER_GROUPING_USED, I18N_UNUMBER_DECIMAL_ALWAYS_SHOWN, I18N_UNUMBER_MAX_INTEGER_DIGITS, I18N_UNUMBER_MIN_INTEGER_DIGITS, I18N_UNUMBER_INTEGER_DIGITS, I18N_UNUMBER_MAX_FRACTION_DIGITS, I18N_UNUMBER_MIN_FRACTION_DIGITS, I18N_UNUMBER_FRACTION_DIGITS, I18N_UNUMBER_MULTIPLIER, I18N_UNUMBER_GROUPING_SIZE, I18N_UNUMBER_ROUNDING_MODE, I18N_UNUMBER_FORMAT_WIDTH, I18N_UNUMBER_PADDING_POSITION, I18N_UNUMBER_SECONDARY_GROUPING_SIZE, I18N_UNUMBER_SIGNIFICANT_DIGITS_USED, I18N_UNUMBER_MIN_SIGNIFICANT_DIGITS, I18N_UNUMBER_MAX_SIGNIFICANT_DIGITS, I18N_UNUMBER_LENIENT_PARSE, I18N_UNUM_SCALE, I18N_UNUM_FORMAT_FAIL_IF_MORE_THAN_MAX_DIGITS, I18N_UNUM_PARSE_NO_EXPONENT.
[in]	new_value	The new value of attr.

Returns:

The obtained error code.

Return values:

I18N_ERROR_NONE	Successful.
I18N_ERROR_INVALID_PARAMETER	Invalid function parameter
I18N_ERROR_NOT_SUPPORTED	Not supported

Sets a numeric attribute associated with an i18n_unumber_format_h.

An example of a numeric attribute is the number of integer digits a formatter will produce. If the formatter does not understand the attribute, this call is ignored.

Remarks:

Error codes are described in i18n_error_code_e description.

Since :

2.3.1

Parameters:

[in]	fmt	The formatter to set.
[in]	attr	The attribute to query; Only I18N_UNUMBER_ROUNDING_INCREMENT is supported.
[in]	new_value	The new value of attr.

Returns:

The obtained error code.

Return values:

I18N_ERROR_NONE	Successful.
I18N_ERROR_INVALID_PARAMETER	Invalid function parameter

Sets a symbol associated with an i18n_unumber_format_h.

An i18n_unumber_format_h uses symbols to represent the special locale-dependent characters in a number, for example the percent sign. This API is not supported for rule-based formatters.

Remarks:

Error codes are described in i18n_error_code_e description.

Since :

2.3.1

Parameters:

[in]	fmt	The formatter to set.
[in]	symbol	The i18n_unumber_format_symbol_e constant for the symbol to set
[in]	value	The string to set the symbol to
[in]	length	The length of the input string, or -1 for a zero-terminated string

Returns:

The obtained error code.

Return values:

I18N_ERROR_NONE	Successful.
I18N_ERROR_INVALID_PARAMETER	Invalid function parameter

Sets a text attribute associated with an i18n_unumber_format_h.

An example of a text attribute is the suffix for positive numbers. Rule-based formatters only understand I18N_UNUMBER_DEFAULT_RULESET. The I18N_UNUMBER_PUBLIC_RULESETS tag is not supported.

Remarks:

Error codes are described in i18n_error_code_e description.

Since :

2.3.1

Parameters:

[in]	fmt	The formatter to set.
[in]	tag	The attribute to set; one of I18N_UNUMBER_POSITIVE_PREFIX, I18N_UNUMBER_POSITIVE_SUFFIX, I18N_UNUMBER_NEGATIVE_PREFIX, I18N_UNUMBER_NEGATIVE_SUFFIX, I18N_UNUMBER_PADDING_CHARACTER, I18N_UNUMBER_CURRENCY_CODE, I18N_UNUMBER_DEFAULT_RULESET.
[in]	new_value	The new value of tag.
[in]	new_value_length	The length of new_value, or -1 if NULL-terminated.

Returns:

The obtained error code.

Return values:

I18N_ERROR_NONE	Successful.
I18N_ERROR_INVALID_PARAMETER	Invalid function parameter

Extracts the pattern from an i18n_unumber_format_h.

The pattern will follow the DecimalFormat pattern syntax.

Remarks:

The specific error code can be obtained using the get_last_result() method. Error codes are described in Exceptions section and i18n_error_code_e description.

Since :

2.3.1

Parameters:

[in]	fmt	The formatter to query.
[in]	is_pattern_localized	true if the pattern should be localized, false otherwise. This is ignored if the formatter is a rule-based formatter.
[out]	result	A pointer to a buffer to receive the pattern.
[in]	result_length	The maximum size of result.

Returns:

The total buffer size needed; if greater than result_length, the output was truncated.

Exceptions:

I18N_ERROR_NONE	Successful
I18N_ERROR_INVALID_PARAMETER	Invalid function parameter
