6085 =head1 Locale-related functions and macros
6087 =for apidoc Amn|void|DECLARATION_FOR_LC_NUMERIC_MANIPULATION
6089 This macro should be used as a statement. It declares a private variable
6090 (whose name begins with an underscore) that is needed by the other macros in
6091 this section. Failing to include this correctly should lead to a syntax error.
6092 For compatibility with C89 C compilers it should be placed in a block before
6093 any executable statements.
6095 =for apidoc Am|void|STORE_LC_NUMERIC_FORCE_TO_UNDERLYING
6097 This is used by XS code that that is C<LC_NUMERIC> locale-aware to force the
6098 locale for category C<LC_NUMERIC> to be what perl thinks is the current
6099 underlying locale. (The perl interpreter could be wrong about what the
6100 underlying locale actually is if some C or XS code has called the C library
6101 function L<setlocale(3)> behind its back; calling L</sync_locale> before calling
6102 this macro will update perl's records.)
6104 A call to L</DECLARATION_FOR_LC_NUMERIC_MANIPULATION> must have been made to
6105 declare at compile time a private variable used by this macro. This macro
6106 should be called as a single statement, not an expression, but with an empty
6107 argument list, like this:
6110 DECLARATION_FOR_LC_NUMERIC_MANIPULATION;
6112 STORE_LC_NUMERIC_FORCE_TO_UNDERLYING();
6114 RESTORE_LC_NUMERIC();
6118 The private variable is used to save the current locale state, so
6119 that the requisite matching call to L</RESTORE_LC_NUMERIC> can restore it.
6121 =for apidoc Am|void|STORE_LC_NUMERIC_SET_TO_NEEDED
6123 This is used to help wrap XS or C code that that is C<LC_NUMERIC> locale-aware.
6124 This locale category is generally kept set to the C locale by Perl for
6125 backwards compatibility, and because most XS code that reads floating point
6126 values can cope only with the decimal radix character being a dot.
6128 This macro makes sure the current C<LC_NUMERIC> state is set properly, to be
6129 aware of locale if the call to the XS or C code from the Perl program is
6130 from within the scope of a S<C<use locale>>; or to ignore locale if the call is
6131 instead from outside such scope.
6133 This macro is the start of wrapping the C or XS code; the wrap ending is done
6134 by calling the L</RESTORE_LC_NUMERIC> macro after the operation. Otherwise
6135 the state can be changed that will adversely affect other XS code.
6137 A call to L</DECLARATION_FOR_LC_NUMERIC_MANIPULATION> must have been made to
6138 declare at compile time a private variable used by this macro. This macro
6139 should be called as a single statement, not an expression, but with an empty
6140 argument list, like this:
6143 DECLARATION_FOR_LC_NUMERIC_MANIPULATION;
6145 STORE_LC_NUMERIC_SET_TO_NEEDED();
6147 RESTORE_LC_NUMERIC();
6151 =for apidoc Am|void|RESTORE_LC_NUMERIC
6153 This is used in conjunction with one of the macros
6154 L</STORE_LC_NUMERIC_SET_TO_NEEDED>
6156 L</STORE_LC_NUMERIC_FORCE_TO_UNDERLYING>
6158 to properly restore the C<LC_NUMERIC> state.
6160 A call to L</DECLARATION_FOR_LC_NUMERIC_MANIPULATION> must have been made to
6161 declare at compile time a private variable used by this macro and the two
6162 C<STORE> ones. This macro should be called as a single statement, not an
6163 expression, but with an empty argument list, like this:

6904 * To back up a bit (harhar):
6906 * For IEEE 754 64-bit formats [1]:
6908 * s 000 (mantissa all-zero) zero
6909 * s 000 (mantissa non-zero) subnormals (denormals)
6910 * s 001 ... 7fe normals
6913 * For IEEE 754 128-bit formats:
6915 * s 0000 (mantissa all-zero) zero
6916 * s 0000 (mantissa non-zero) subnormals (denormals)
6917 * s 0001 ... 7ffe normals
6920 * [1] this looks like big-endian, but applies equally to little-endian.
6922 * s = Sign bit. Yes, zeros and nans can have negative sign,
6923 * the interpretation is application-specific.
6925 * q = Quietness bit, the interpretation is platform-specific.
6926 * Most platforms have the most significant bit being one
6927 * meaning quiet, but some (older mips, hppa) have the msb
6928 * being one meaning signaling. Note that the above means
6929 * that on most platforms there cannot be signaling nan with
6930 * zero payload because that is identical with infinity;
6931 * while conversely on older mips/hppa there cannot be a quiet nan
6932 * because that is identical with infinity.
6934 * Moreover, whether there is any behavioral difference
6935 * between quiet and signaling NaNs, depends on the platform.
6937 * x86 80-bit extended precision is different, the mantissa bits:
6939 * 63 62 61 30387+ pre-387 visual c
6940 * -------- ---- -------- --------
6941 * 0 0 0 invalid infinity
6942 * 0 0 1 invalid snan
6943 * 0 1 0 invalid snan
6944 * 0 1 1 invalid snan
6945 * 1 0 0 infinity snan 1.#INF
6946 * 1 0 1 snan 1.#SNAN
6947 * 1 1 0 qnan -1.#IND (x86 chooses this to negative)
6948 * 1 1 1 qnan 1.#QNAN
6950 * This means that in this format there are 61 bits available
6951 * for the nan payload.
6953 * Note that the 32-bit x86 ABI cannot do signaling nans: the x87
6954 * simply cannot preserve the bit. You can either use the 80-bit
6955 * extended precision (long double, -Duselongdouble), or use x86-64.
6957 * In all platforms, the payload bytes (and bits, some of them are
6958 * often in a partial byte) themselves can be either all zero (x86),
6959 * all one (sparc or mips), or a mixture: in IEEE 754 128-bit double
6960 * or in a double-double, the first half of the payload can follow the
6961 * native double, while in the second half the payload can be all
6962 * zeros. (Therefore the mask for payload bits is not necessarily
6963 * identical to bit complement of the NaN.) Another way of putting
6964 * this: the payload for the default NaN might not be zero.
6966 * For the x86 80-bit long doubles, the trailing bytes (the 80 bits
6967 * being 'packaged' in either 12 or 16 bytes) can be whatever random
6970 * Furthermore, the semantics of the sign bit on NaNs are platform-specific.
6971 * On normal floats, the sign bit being on means negative. But this may,
6972 * or may not, be reverted on NaNs: in other words, the default NaN might
6973 * have the sign bit on, and therefore look like negative if you look
6974 * at it at the bit level.
6976 * NaN payloads are not propagated even on copies, or in arithmetics.
6977 * They *might* be, according to some rules, on your particular
6978 * cpu/os/compiler/libraries, but no guarantees.
6980 * To summarize, on most platforms, and for 64-bit doubles
6981 * (using big-endian ordering here):
6983 * [7FF8000000000000..7FFFFFFFFFFFFFFF] quiet
6984 * [FFF8000000000000..FFFFFFFFFFFFFFFF] quiet
6985 * [7FF0000000000001..7FF7FFFFFFFFFFFF] signaling
6986 * [FFF0000000000001..FFF7FFFFFFFFFFFF] signaling
6988 * The C99 nan() is supposed to generate *quiet* NaNs.
6990 * Note the asymmetry:
6991 * The 7FF0000000000000 is positive infinity,
6992 * the FFF0000000000000 is negative infinity.
6995 /* NVMANTBITS is the number of _real_ mantissa bits in an NV.
6996 * For the standard IEEE 754 fp this number is usually one less that
6997 * *DBL_MANT_DIG because of the implicit (aka hidden) bit, which isn't
6998 * real. For the 80-bit extended precision formats (x86*), the number
6999 * of mantissa bits... depends. For normal floats, it's 64. But for
