Re: [icu-design] #9592 C: Max Integer control, Exponent Case Sensitivity Control (updated)

[<yos...@us...>]

The proposal below was approved by the ICU PMC on 2012-10-03 with one 
update.

 /** If nonzero, specifies that if setting the "max integer digits" 
attribute would truncate a value, return a format error rather than 
silently truncating.
  * For example,  formatting "1234" with 4 max int digits would succeed, 
but "12345" would fail. No effect on parsing.
  * @draft ICU 50
  */
 UNUM_FORMAT_FAIL_IF_MAX_DIGITS,


The name of enum was changed to UNUM_FORMAT_FAIL_IF_MORE_THAN_MAX_DIGITS 
to avoid some confusion. Therefore, the final API signature will be -

 /** If nonzero, specifies that if setting the "max integer digits" 
attribute would truncate a value, return a format error rather than 
silently truncating.
  * For example,  formatting "1234" with 4 max int digits would succeed, 
but "12345" would fail. No effect on parsing.
  * @draft ICU 50
  */
 UNUM_FORMAT_FAIL_IF_MORE_THAN_MAX_DIGITS,

Thanks,
Yoshito

Case Sensitivity Control (updated)



9592: Decimal Format Max Integer Control, Case Sensitivity Control 
[pending]
Steven
Proposer: Steven
I would like to propose the following API for: ICU 50
Please provide feedback by: next Wednesday, 2012-10-03
Designated API reviewer: Yoshito
Ticket: http://bugs.icu-project.org/trac/ticket/9592

#1 Max Integer Control

TODO: max digits: Find out current behavior (format, parse) x (C++, Java) 
and revisit
Results: C and J:  “1997” with max int digits  2 parses as “97”.  Has no 
effect on formatting.

#2 Case Sensitivity Control
Affect all text. Parse only.


unum.h:

enum UNumberFormatAttribute {
 /** If nonzero, specifies that if setting the "max integer digits" 
attribute would truncate a value, return a format error rather than 
silently truncating.
  * For example,  formatting "1234" with 4 max int digits would succeed, 
but "12345" would fail. No effect on parsing.
  * @draft ICU 50
  */
 UNUM_FORMAT_FAIL_IF_MAX_DIGITS,

 /** If nonzero, specifies that any text is parsed in a case-sensitive 
way.  By default, some items, such as the exponent symbol, are parsed 
case-insensitive.
  * @draft ICU 50
  */
 UNUM_PARSE_CASE_SENSITIVE,
}




No special C++ API. See #9613
