+ \class QLocale
+ \brief The QLocale 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 QString.
+
+ \code
+ QLocale egyptian(QLocale::Arabic, QLocale::Egypt);
+ QString s1 = egyptian.toString(1.571429E+07, 'e');
+ QString s2 = egyptian.toString(10);
+
+ double d = egyptian.toDouble(s1);
+ int s2 = egyptian.toInt(s2);
+ \endcode
+
+ QLocale 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 QLocale object is constructed with the default constructor,
+ it will use the default locale's settings.
+ \i QString::toDouble() interprets the string according to the default
+ locale. If this fails, it falls back on the "C" locale.
+ \i QString::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
+ QLocale::setDefault(QLocale::Hebrew, QLocale::Israel);
+ QLocale hebrew; // Constructs a default QLocale
+ QString s1 = hebrew.toString(15714.3, 'e');
+
+ bool ok;
+ double d;
+
+ QLocale::setDefault(QLocale::C);
+ d = QString( "1234,56" ).toDouble(&ok); // ok == false
+ d = QString( "1234.56" ).toDouble(&ok); // ok == true, d == 1234.56
+
+ QLocale::setDefault(QLocale::German);
+ d = QString( "1234,56" ).toDouble(&ok); // ok == true, d == 1234.56
+ d = QString( "1234.56" ).toDouble(&ok); // ok == true, d == 1234.56
+
+ QLocale::setDefault(QLocale::English, QLocale::UnitedStates);
+ str = QString( "%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, QLocale
+ 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 QLocale object is by
+ specifying the locale name.
+
+ \code
+ QLocale korean("ko");
+ QLocale 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 QLocale, 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).

+/* dtoa for IEEE arithmetic (dmg): convert double to ASCII string.
+ *
+ * Inspired by "How to Print Floating-Point Numbers Accurately" by
+ * Guy L. Steele, Jr. and Jon L. White [Proc. ACM SIGPLAN '90, pp. 92-101].
+ *
+ * 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,
+ * mode 0 renders 1e23 as 1e23 rather than 9.999999999999999e22.
+ * That is, we allow equality in stopping tests when the
+ * round-nearest rule will give the same floating-point value
+ * as would satisfaction of the stopping test with strict
+ * inequality.
+ * 4. We remove common factors of powers of 2 from relevant
+ * quantities.
+ * 5. When converting floating-point integers less than 1e16,
+ * we use floating-point arithmetic rather than resorting
+ * to multiple-precision integers.
+ * 6. When asked to produce fewer than 15 digits, we first try
+ * to get by with floating-point arithmetic; we resort to
+ * multiple-precision integer arithmetic only if we cannot
+ * guarantee that the floating-point calculation has given
+ * the correctly rounded result. For k requested digits and
+ * "uniformly" distributed input, the probability is
+ * something like 10^(k-15) that we must resort to the Long
+ * calculation.

+ then *decpt is set to 9999.
+
+ mode:
+ 0 ==> shortest string that yields d when read in
+ and rounded to nearest.
+ 1 ==> like 0, but with Steele & White stopping rule;
+ 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
+ gives a return value similar to that from fcvt,
+ except that trailing zeros are suppressed, and
+ ndigits can be negative.
+ 4-9 should give the same return values as 2-3, i.e.,
+ 4 <= mode <= 9 ==> same return as mode
+ 2 + (mode & 1). These modes are mainly for
+ 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.
