\class TQLocale
|
|
|
|
\brief The TQLocale class converts between numbers and their
|
|
|
|
string representations in various languages.
|
|
|
|
|
|
|
|
\reentrant
|
|
|
|
\ingroup text
|
|
|
|
|
|
|
|
It is initialized with a country/language pair in its constructor
|
|
|
|
and offers number-to-string and string-to-number conversion
|
|
|
|
functions simmilar to those in TQString.
|
|
|
|
|
|
|
|
\code
|
|
|
|
TQLocale egyptian(TQLocale::Arabic, TQLocale::Egypt);
|
|
|
|
TQString s1 = egyptian.toString(1.571429E+07, 'e');
|
|
|
|
TQString s2 = egyptian.toString(10);
|
|
|
|
|
|
|
|
double d = egyptian.toDouble(s1);
|
|
|
|
int s2 = egyptian.toInt(s2);
|
|
|
|
\endcode
|
|
|
|
|
|
|
|
TQLocale supports the concept of a default locale, which is
|
|
|
|
determined from the system's locale settings at application
|
|
|
|
startup. The default locale can be changed by calling the
|
|
|
|
static member setDefault(). The default locale has the
|
|
|
|
following effects:
|
|
|
|
|
|
|
|
\list
|
|
|
|
\i If a TQLocale object is constructed with the default constructor,
|
|
|
|
it will use the default locale's settings.
|
|
|
|
\i TQString::toDouble() interprets the string according to the default
|
|
|
|
locale. If this fails, it falls back on the "C" locale.
|
|
|
|
\i TQString::arg() uses the default locale to format a number when
|
|
|
|
its position specifier in the format string contains an 'L',
|
|
|
|
e.g. "%L1".
|
|
|
|
\endlist
|
|
|
|
|
|
|
|
\code
|
|
|
|
TQLocale::setDefault(TQLocale(TQLocale::Hebrew, TQLocale::Israel));
|
|
|
|
TQLocale hebrew; // Constructs a default TQLocale
|
|
|
|
TQString s1 = hebrew.toString(15714.3, 'e');
|
|
|
|
|
|
|
|
bool ok;
|
|
|
|
double d;
|
|
|
|
|
|
|
|
TQLocale::setDefault(TQLocale::C);
|
|
|
|
d = TQString( "1234,56" ).toDouble(&ok); // ok == false
|
|
|
|
d = TQString( "1234.56" ).toDouble(&ok); // ok == true, d == 1234.56
|
|
|
|
|
|
|
|
TQLocale::setDefault(TQLocale::German);
|
|
|
|
d = TQString( "1234,56" ).toDouble(&ok); // ok == true, d == 1234.56
|
|
|
|
d = TQString( "1234.56" ).toDouble(&ok); // ok == true, d == 1234.56
|
|
|
|
|
|
|
|
TQLocale::setDefault(TQLocale(TQLocale::English, TQLocale::UnitedStates));
|
|
|
|
str = TQString( "%1 %L2 %L3" )
|
|
|
|
.arg( 12345 )
|
|
|
|
.arg( 12345 )
|
|
|
|
.arg( 12345, 0, 16 );
|
|
|
|
// str == "12345 12,345 3039"
|
|
|
|
\endcode
|
|
|
|
|
|
|
|
When a language/country pair is specified in the constructor, one
|
|
|
|
of three things can happen:
|
|
|
|
|
|
|
|
\list
|
|
|
|
\i If the language/country pair is found in the database, it is used.
|
|
|
|
\i If the language is found but the country is not, or if the country
|
|
|
|
is \c AnyCountry, the language is used with the most
|
|
|
|
appropriate available country (for example, Germany for German),
|
|
|
|
\i If neither the language nor the country are found, TQLocale
|
|
|
|
defaults to the default locale (see setDefault()).
|
|
|
|
\endlist
|
|
|
|
|
|
|
|
The "C" locale is identical to English/UnitedStates.
|
|
|
|
|
|
|
|
Use language() and country() to determine the actual language and
|
|
|
|
country values used.
|
|
|
|
|
|
|
|
An alternative method for constructing a TQLocale object is by
|
|
|
|
specifying the locale name.
|
|
|
|
|
|
|
|
\code
|
|
|
|
TQLocale korean("ko");
|
|
|
|
TQLocale swiss("de_CH");
|
|
|
|
\endcode
|
|
|
|
|
|
|
|
This constructor converts the locale name to a language/country
|
|
|
|
pair; it does not use the system locale database.
|
|
|
|
|
|
|
|
All the methods in TQLocale, with the exception of setDefault(),
|
|
|
|
are reentrant.

/* strtod for IEEE-, VAX-, and IBM-arithmetic machines.
|
|
|
|
*
|
|
|
|
* This strtod returns a nearest machine number to the input decimal
|
|
|
|
* string (or sets errno to ERANGE). With IEEE arithmetic, ties are
|
|
|
|
* broken by the IEEE round-even rule. Otherwise ties are broken by
|
|
|
|
* biased rounding (add half and chop).
|
|
|
|
*
|
|
|
|
* Inspired loosely by William D. Clinger's paper "How to Read Floating
|
|
|
|
* Point Numbers Accurately" [Proc. ACM SIGPLAN '90, pp. 92-101].
|
|
|
|
*
|
|
|
|
* Modifications:
|
|
|
|
*
|
|
|
|
* 1. We only require IEEE, IBM, or VAX double-precision
|
|
|
|
* arithmetic (not IEEE double-extended).
|
|
|
|
* 2. We get by with floating-point arithmetic in a case that
|
|
|
|
* Clinger missed -- when we're computing d * 10^n
|
|
|
|
* for a small integer d and the integer n is not too
|
|
|
|
* much larger than 22 (the maximum integer k for which
|
|
|
|
* we can represent 10^k exactly), we may be able to
|
|
|
|
* compute (d*10^k) * 10^(e-k) with just one roundoff.
|
|
|
|
* 3. Rather than a bit-at-a-time adjustment of the binary
|
|
|
|
* result in the hard case, we use floating-point
|
|
|
|
* arithmetic to determine the adjustment to within
|
|
|
|
* one bit; only in really hard cases do we need to
|
|
|
|
* compute a second residual.
|
|
|
|
* 4. Because of 3., we don't need a large table of powers of 10
|
|
|
|
* for ten-to-e (just some small tables, e.g. of 10^k
|
|
|
|
* for 0 <= k <= 22).

* Inspired by "How to Print Floating-Point Numbers Accurately" by

|
|
* Modifications:
|
|
|
|
* 1. Rather than iterating, we use a simple numeric overestimate
|
|
|
|
* to determine k = floor(log10(d)). We scale relevant
|
|
|
|
* quantities using O(log2(k)) rather than O(k) multiplications.
|
|
|
|
* 2. For some modes > 2 (corresponding to ecvt and fcvt), we don't
|
|
|
|
* try to generate digits strictly left to right. Instead, we
|
|
|
|
* compute with fewer bits and propagate the carry if necessary
|
|
|
|
* when rounding the final digit up. This is often faster.
|
|
|
|
* 3. Under the assumption that input will be rounded nearest,

e.g. with IEEE P754 arithmetic , mode 0 gives

1e23 whereas mode 1 gives 9.999999999999999e22.

2 ==> max(1,ndigits) significant digits. This gives a

return value similar to that of ecvt, except

that trailing zeros are suppressed.

3 ==> through ndigits past the decimal point. This

ndigits can be negative.

debugging; often they run slower but sometimes

faster than modes 2-3.

4,5,8,9 ==> left-to-right digit generation.

|
|
6-9 ==> don't try fast floating-point estimate
|
|
|
|
(if applicable).
|
|
|
|
|
|
|
|
Values of mode other than 0-9 are treated as mode 0.
|
|
|

|
|

Sufficient space is allocated to the return value
|
|
|
|
to hold the suppressed trailing zeros.
