    \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).

/* 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.

      mode:

      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.

      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.
