6071 =head1 Locale-related functions and macros
6073 =for apidoc Amn|void|DECLARATION_FOR_LC_NUMERIC_MANIPULATION
6075 This macro should be used as a statement. It declares a private variable
6076 (whose name begins with an underscore) that is needed by the other macros in
6077 this section. Failing to include this correctly should lead to a syntax error.
6078 For compatibility with C89 C compilers it should be placed in a block before
6079 any executable statements.
6081 =for apidoc Am|void|STORE_LC_NUMERIC_FORCE_TO_UNDERLYING
6083 This is used by XS code that that is C<LC_NUMERIC> locale-aware to force the
6084 locale for category C<LC_NUMERIC> to be what perl thinks is the current
6085 underlying locale. (The perl interpreter could be wrong about what the
6086 underlying locale actually is if some C or XS code has called the C library
6087 function L<setlocale(3)> behind its back; calling L</sync_locale> before calling
6088 this macro will update perl's records.)
6090 A call to L</DECLARATION_FOR_LC_NUMERIC_MANIPULATION> must have been made to
6091 declare at compile time a private variable used by this macro. This macro
6092 should be called as a single statement, not an expression, but with an empty
6093 argument list, like this:
6096 DECLARATION_FOR_LC_NUMERIC_MANIPULATION;
6098 STORE_LC_NUMERIC_FORCE_TO_UNDERLYING();
6100 RESTORE_LC_NUMERIC();
6104 The private variable is used to save the current locale state, so
6105 that the requisite matching call to L</RESTORE_LC_NUMERIC> can restore it.
6107 =for apidoc Am|void|STORE_LC_NUMERIC_SET_TO_NEEDED
6109 This is used to help wrap XS or C code that that is C<LC_NUMERIC> locale-aware.
6110 This locale category is generally kept set to the C locale by Perl for
6111 backwards compatibility, and because most XS code that reads floating point
6112 values can cope only with the decimal radix character being a dot.
6114 This macro makes sure the current C<LC_NUMERIC> state is set properly, to be
6115 aware of locale if the call to the XS or C code from the Perl program is
6116 from within the scope of a S<C<use locale>>; or to ignore locale if the call is
6117 instead from outside such scope.
6119 This macro is the start of wrapping the C or XS code; the wrap ending is done
6120 by calling the L</RESTORE_LC_NUMERIC> macro after the operation. Otherwise
6121 the state can be changed that will adversely affect other XS code.
6123 A call to L</DECLARATION_FOR_LC_NUMERIC_MANIPULATION> must have been made to
6124 declare at compile time a private variable used by this macro. This macro
6125 should be called as a single statement, not an expression, but with an empty
6126 argument list, like this:
6129 DECLARATION_FOR_LC_NUMERIC_MANIPULATION;
6131 STORE_LC_NUMERIC_SET_TO_NEEDED();
6133 RESTORE_LC_NUMERIC();
6137 =for apidoc Am|void|RESTORE_LC_NUMERIC
6139 This is used in conjunction with one of the macros
6140 L</STORE_LC_NUMERIC_SET_TO_NEEDED>
6142 L</STORE_LC_NUMERIC_FORCE_TO_UNDERLYING>
6144 to properly restore the C<LC_NUMERIC> state.
6146 A call to L</DECLARATION_FOR_LC_NUMERIC_MANIPULATION> must have been made to
6147 declare at compile time a private variable used by this macro and the two
6148 C<STORE> ones. This macro should be called as a single statement, not an
6149 expression, but with an empty argument list, like this:

6823 /* NaNs (not-a-numbers) can carry payload bits, in addition to
6824 * "nan-ness". Part of the payload is the quiet/signaling bit.
6825 * To back up a bit (harhar):
6827 * For IEEE 754 64-bit formats [1]:
6829 * s 000 (mantissa all-zero) zero
6830 * s 000 (mantissa non-zero) subnormals (denormals)
6831 * s 001 ... 7fe normals
6834 * For IEEE 754 128-bit formats:
6836 * s 0000 (mantissa all-zero) zero
6837 * s 0000 (mantissa non-zero) subnormals (denormals)
6838 * s 0001 ... 7ffe normals
6841 * [1] this looks like big-endian, but applies equally to little-endian.
6843 * s = Sign bit. Yes, zeros and nans can have negative sign,
6844 * the interpretation is application-specific.
6846 * q = Quietness bit, the interpretation is platform-specific.
6847 * Most platforms have the most significant bit being one
6848 * meaning quiet, but some (older mips, hppa) have the msb
6849 * being one meaning signaling. Note that the above means
6850 * that on most platforms there cannot be signaling nan with
6851 * zero payload because that is identical with infinity;
6852 * while conversely on older mips/hppa there cannot be a quiet nan
6853 * because that is identical with infinity.
6855 * Moreover, whether there is any behavioral difference
6856 * between quiet and signaling NaNs, depends on the platform.
6858 * x86 80-bit extended precision is different, the mantissa bits:
6860 * 63 62 61 30387+ pre-387 visual c
6861 * -------- ---- -------- --------
6862 * 0 0 0 invalid infinity
6863 * 0 0 1 invalid snan
6864 * 0 1 0 invalid snan
6865 * 0 1 1 invalid snan
6866 * 1 0 0 infinity snan 1.#INF
6867 * 1 0 1 snan 1.#SNAN
6868 * 1 1 0 qnan -1.#IND (x86 chooses this to negative)
6869 * 1 1 1 qnan 1.#QNAN
6871 * This means that in this format there are 61 bits available
6872 * for the nan payload.
6874 * Note that the 32-bit x86 ABI cannot do signaling nans: the x87
6875 * simply cannot preserve the bit. You can either use the 80-bit
6876 * extended precision (long double, -Duselongdouble), or use x86-64.
6878 * In all platforms, the payload bytes (and bits, some of them are
6879 * often in a partial byte) themselves can be either all zero (x86),
6880 * all one (sparc or mips), or a mixture: in IEEE 754 128-bit double
6881 * or in a double-double, the first half of the payload can follow the
6882 * native double, while in the second half the payload can be all
6883 * zeros. (Therefore the mask for payload bits is not necessarily
6884 * identical to bit complement of the NaN.) Another way of putting
6885 * this: the payload for the default NaN might not be zero.
6887 * For the x86 80-bit long doubles, the trailing bytes (the 80 bits
6888 * being 'packaged' in either 12 or 16 bytes) can be whatever random
6891 * Furthermore, the semantics of the sign bit on NaNs are platform-specific.
6892 * On normal floats, the sign bit being on means negative. But this may,
6893 * or may not, be reverted on NaNs: in other words, the default NaN might
6894 * have the sign bit on, and therefore look like negative if you look
6895 * at it at the bit level.
6897 * NaN payloads are not propagated even on copies, or in arithmetics.
6898 * They *might* be, according to some rules, on your particular
6899 * cpu/os/compiler/libraries, but no guarantees.
6901 * To summarize, on most platforms, and for 64-bit doubles
6902 * (using big-endian ordering here):
6904 * [7FF8000000000000..7FFFFFFFFFFFFFFF] quiet
6905 * [FFF8000000000000..FFFFFFFFFFFFFFFF] quiet
6906 * [7FF0000000000001..7FF7FFFFFFFFFFFF] signaling
6907 * [FFF0000000000001..FFF7FFFFFFFFFFFF] signaling
6909 * The C99 nan() is supposed to generate *quiet* NaNs.
6911 * Note the asymmetry:
6912 * The 7FF0000000000000 is positive infinity,
6913 * the FFF0000000000000 is negative infinity.
6916 /* NVMANTBITS is the number of _real_ mantissa bits in an NV.
6917 * For the standard IEEE 754 fp this number is usually one less that
6918 * *DBL_MANT_DIG because of the implicit (aka hidden) bit, which isn't
6919 * real. For the 80-bit extended precision formats (x86*), the number
6920 * of mantissa bits... depends. For normal floats, it's 64. But for
6921 * the inf/nan, it's different (zero for inf, 61 for nan).
6922 * NVMANTBITS works for normal floats. */
