6130 =for apidoc Amn|void|DECLARATION_FOR_LC_NUMERIC_MANIPULATION
6132 This macro should be used as a statement. It declares a private variable
6133 (whose name begins with an underscore) that is needed by the other macros in
6134 this section. Failing to include this correctly should lead to a syntax error.
6135 For compatibility with C89 C compilers it should be placed in a block before
6136 any executable statements.
6138 =for apidoc Am|void|STORE_LC_NUMERIC_FORCE_TO_UNDERLYING
6140 This is used by XS code that that is C<LC_NUMERIC> locale-aware to force the
6141 locale for category C<LC_NUMERIC> to be what perl thinks is the current
6142 underlying locale. (The perl interpreter could be wrong about what the
6143 underlying locale actually is if some C or XS code has called the C library
6144 function L<setlocale(3)> behind its back; calling L</sync_locale> before calling
6145 this macro will update perl's records.)
6147 A call to L</DECLARATION_FOR_LC_NUMERIC_MANIPULATION> must have been made to
6148 declare at compile time a private variable used by this macro. This macro
6149 should be called as a single statement, not an expression, but with an empty
6150 argument list, like this:
6153 DECLARATION_FOR_LC_NUMERIC_MANIPULATION;
6155 STORE_LC_NUMERIC_FORCE_TO_UNDERLYING();
6157 RESTORE_LC_NUMERIC();
6161 The private variable is used to save the current locale state, so
6162 that the requisite matching call to L</RESTORE_LC_NUMERIC> can restore it.
6164 =for apidoc Am|void|STORE_LC_NUMERIC_SET_TO_NEEDED
6166 This is used to help wrap XS or C code that that is C<LC_NUMERIC> locale-aware.
6167 This locale category is generally kept set to the C locale by Perl for
6168 backwards compatibility, and because most XS code that reads floating point
6169 values can cope only with the decimal radix character being a dot.
6171 This macro makes sure the current C<LC_NUMERIC> state is set properly, to be
6172 aware of locale if the call to the XS or C code from the Perl program is
6173 from within the scope of a S<C<use locale>>; or to ignore locale if the call is
6174 instead from outside such scope.
6176 This macro is the start of wrapping the C or XS code; the wrap ending is done
6177 by calling the L</RESTORE_LC_NUMERIC> macro after the operation. Otherwise
6178 the state can be changed that will adversely affect other XS code.
6180 A call to L</DECLARATION_FOR_LC_NUMERIC_MANIPULATION> must have been made to
6181 declare at compile time a private variable used by this macro. This macro
6182 should be called as a single statement, not an expression, but with an empty
6183 argument list, like this:
6186 DECLARATION_FOR_LC_NUMERIC_MANIPULATION;
6188 STORE_LC_NUMERIC_SET_TO_NEEDED();
6190 RESTORE_LC_NUMERIC();
6194 =for apidoc Am|void|RESTORE_LC_NUMERIC
6196 This is used in conjunction with one of the macros
6197 L</STORE_LC_NUMERIC_SET_TO_NEEDED>
6199 L</STORE_LC_NUMERIC_FORCE_TO_UNDERLYING>
6201 to properly restore the C<LC_NUMERIC> state.
6203 A call to L</DECLARATION_FOR_LC_NUMERIC_MANIPULATION> must have been made to
6204 declare at compile time a private variable used by this macro and the two
6205 C<STORE> ones. This macro should be called as a single statement, not an
6206 expression, but with an empty argument list, like this:

6969 * To back up a bit (harhar):
6971 * For IEEE 754 64-bit formats [1]:
6973 * s 000 (mantissa all-zero) zero
6974 * s 000 (mantissa non-zero) subnormals (denormals)
6975 * s 001 ... 7fe normals
6978 * For IEEE 754 128-bit formats:
6980 * s 0000 (mantissa all-zero) zero
6981 * s 0000 (mantissa non-zero) subnormals (denormals)
6982 * s 0001 ... 7ffe normals
6985 * [1] this looks like big-endian, but applies equally to little-endian.
6987 * s = Sign bit. Yes, zeros and nans can have negative sign,
6988 * the interpretation is application-specific.
6990 * q = Quietness bit, the interpretation is platform-specific.
6991 * Most platforms have the most significant bit being one
6992 * meaning quiet, but some (older mips, hppa) have the msb
6993 * being one meaning signaling. Note that the above means
6994 * that on most platforms there cannot be signaling nan with
6995 * zero payload because that is identical with infinity;
6996 * while conversely on older mips/hppa there cannot be a quiet nan
6997 * because that is identical with infinity.
6999 * Moreover, whether there is any behavioral difference
7000 * between quiet and signaling NaNs, depends on the platform.
7002 * x86 80-bit extended precision is different, the mantissa bits:
7004 * 63 62 61 30387+ pre-387 visual c
7005 * -------- ---- -------- --------
7006 * 0 0 0 invalid infinity
7007 * 0 0 1 invalid snan
7008 * 0 1 0 invalid snan
7009 * 0 1 1 invalid snan
7010 * 1 0 0 infinity snan 1.#INF
7011 * 1 0 1 snan 1.#SNAN
7012 * 1 1 0 qnan -1.#IND (x86 chooses this to negative)
7013 * 1 1 1 qnan 1.#QNAN
7015 * This means that in this format there are 61 bits available
7016 * for the nan payload.
7018 * Note that the 32-bit x86 ABI cannot do signaling nans: the x87
7019 * simply cannot preserve the bit. You can either use the 80-bit
7020 * extended precision (long double, -Duselongdouble), or use x86-64.
7022 * In all platforms, the payload bytes (and bits, some of them are
7023 * often in a partial byte) themselves can be either all zero (x86),
7024 * all one (sparc or mips), or a mixture: in IEEE 754 128-bit double
7025 * or in a double-double, the first half of the payload can follow the
7026 * native double, while in the second half the payload can be all
7027 * zeros. (Therefore the mask for payload bits is not necessarily
7028 * identical to bit complement of the NaN.) Another way of putting
7029 * this: the payload for the default NaN might not be zero.
7031 * For the x86 80-bit long doubles, the trailing bytes (the 80 bits
7032 * being 'packaged' in either 12 or 16 bytes) can be whatever random
7035 * Furthermore, the semantics of the sign bit on NaNs are platform-specific.
7036 * On normal floats, the sign bit being on means negative. But this may,
7037 * or may not, be reverted on NaNs: in other words, the default NaN might
7038 * have the sign bit on, and therefore look like negative if you look
7039 * at it at the bit level.
7041 * NaN payloads are not propagated even on copies, or in arithmetics.
7042 * They *might* be, according to some rules, on your particular
7043 * cpu/os/compiler/libraries, but no guarantees.
7045 * To summarize, on most platforms, and for 64-bit doubles
7046 * (using big-endian ordering here):
7048 * [7FF8000000000000..7FFFFFFFFFFFFFFF] quiet
7049 * [FFF8000000000000..FFFFFFFFFFFFFFFF] quiet
7050 * [7FF0000000000001..7FF7FFFFFFFFFFFF] signaling
7051 * [FFF0000000000001..FFF7FFFFFFFFFFFF] signaling
7053 * The C99 nan() is supposed to generate *quiet* NaNs.
7055 * Note the asymmetry:
7056 * The 7FF0000000000000 is positive infinity,
7057 * the FFF0000000000000 is negative infinity.
7060 /* NVMANTBITS is the number of _real_ mantissa bits in an NV.
7061 * For the standard IEEE 754 fp this number is usually one less that
7062 * *DBL_MANT_DIG because of the implicit (aka hidden) bit, which isn't
7063 * real. For the 80-bit extended precision formats (x86*), the number
7064 * of mantissa bits... depends. For normal floats, it's 64. But for
7065 * the inf/nan, it's different (zero for inf, 61 for nan).
