6034 =for apidoc Amn|void|DECLARATION_FOR_LC_NUMERIC_MANIPULATION
6036 This macro should be used as a statement. It declares a private variable
6037 (whose name begins with an underscore) that is needed by the other macros in
6038 this section. Failing to include this correctly should lead to a syntax error.
6039 For compatibility with C89 C compilers it should be placed in a block before
6040 any executable statements.
6042 =for apidoc Am|void|STORE_LC_NUMERIC_FORCE_TO_UNDERLYING
6044 This is used by XS code that that is C<LC_NUMERIC> locale-aware to force the
6045 locale for category C<LC_NUMERIC> to be what perl thinks is the current
6046 underlying locale. (The perl interpreter could be wrong about what the
6047 underlying locale actually is if some C or XS code has called the C library
6048 function L<setlocale(3)> behind its back; calling L</sync_locale> before calling
6049 this macro will update perl's records.)
6051 A call to L</DECLARATION_FOR_LC_NUMERIC_MANIPULATION> must have been made to
6052 declare at compile time a private variable used by this macro. This macro
6053 should be called as a single statement, not an expression, but with an empty
6054 argument list, like this:
6057 DECLARATION_FOR_LC_NUMERIC_MANIPULATION;
6059 STORE_LC_NUMERIC_FORCE_TO_UNDERLYING();
6061 RESTORE_LC_NUMERIC();
6065 The private variable is used to save the current locale state, so
6066 that the requisite matching call to L</RESTORE_LC_NUMERIC> can restore it.
6068 =for apidoc Am|void|STORE_LC_NUMERIC_SET_TO_NEEDED
6070 This is used to help wrap XS or C code that that is C<LC_NUMERIC> locale-aware.
6071 This locale category is generally kept set to the C locale by Perl for
6072 backwards compatibility, and because most XS code that reads floating point
6073 values can cope only with the decimal radix character being a dot.
6075 This macro makes sure the current C<LC_NUMERIC> state is set properly, to be
6076 aware of locale if the call to the XS or C code from the Perl program is
6077 from within the scope of a S<C<use locale>>; or to ignore locale if the call is
6078 instead from outside such scope.
6080 This macro is the start of wrapping the C or XS code; the wrap ending is done
6081 by calling the L</RESTORE_LC_NUMERIC> macro after the operation. Otherwise
6082 the state can be changed that will adversely affect other XS code.
6084 A call to L</DECLARATION_FOR_LC_NUMERIC_MANIPULATION> must have been made to
6085 declare at compile time a private variable used by this macro. This macro
6086 should be called as a single statement, not an expression, but with an empty
6087 argument list, like this:
6090 DECLARATION_FOR_LC_NUMERIC_MANIPULATION;
6092 STORE_LC_NUMERIC_SET_TO_NEEDED();
6094 RESTORE_LC_NUMERIC();
6098 =for apidoc Am|void|RESTORE_LC_NUMERIC
6100 This is used in conjunction with one of the macros
6101 L</STORE_LC_NUMERIC_SET_TO_NEEDED>
6103 L</STORE_LC_NUMERIC_FORCE_TO_UNDERLYING>
6105 to properly restore the C<LC_NUMERIC> state.
6107 A call to L</DECLARATION_FOR_LC_NUMERIC_MANIPULATION> must have been made to
6108 declare at compile time a private variable used by this macro and the two
6109 C<STORE> ones. This macro should be called as a single statement, not an
6110 expression, but with an empty argument list, like this:

6989 * To back up a bit (harhar):
6991 * For IEEE 754 64-bit formats [1]:
6993 * s 000 (mantissa all-zero) zero
6994 * s 000 (mantissa non-zero) subnormals (denormals)
6995 * s 001 ... 7fe normals
6998 * For IEEE 754 128-bit formats:
7000 * s 0000 (mantissa all-zero) zero
7001 * s 0000 (mantissa non-zero) subnormals (denormals)
7002 * s 0001 ... 7ffe normals
7005 * [1] this looks like big-endian, but applies equally to little-endian.
7007 * s = Sign bit. Yes, zeros and nans can have negative sign,
7008 * the interpretation is application-specific.
7010 * q = Quietness bit, the interpretation is platform-specific.
7011 * Most platforms have the most significant bit being one
7012 * meaning quiet, but some (older mips, hppa) have the msb
7013 * being one meaning signaling. Note that the above means
7014 * that on most platforms there cannot be signaling nan with
7015 * zero payload because that is identical with infinity;
7016 * while conversely on older mips/hppa there cannot be a quiet nan
7017 * because that is identical with infinity.
7019 * Moreover, whether there is any behavioral difference
7020 * between quiet and signaling NaNs, depends on the platform.
7022 * x86 80-bit extended precision is different, the mantissa bits:
7024 * 63 62 61 30387+ pre-387 visual c
7025 * -------- ---- -------- --------
7026 * 0 0 0 invalid infinity
7027 * 0 0 1 invalid snan
7028 * 0 1 0 invalid snan
7029 * 0 1 1 invalid snan
7030 * 1 0 0 infinity snan 1.#INF
7031 * 1 0 1 snan 1.#SNAN
7032 * 1 1 0 qnan -1.#IND (x86 chooses this to negative)
7033 * 1 1 1 qnan 1.#QNAN
7035 * This means that in this format there are 61 bits available
7036 * for the nan payload.
7038 * Note that the 32-bit x86 ABI cannot do signaling nans: the x87
7039 * simply cannot preserve the bit. You can either use the 80-bit
7040 * extended precision (long double, -Duselongdouble), or use x86-64.
7042 * In all platforms, the payload bytes (and bits, some of them are
7043 * often in a partial byte) themselves can be either all zero (x86),
7044 * all one (sparc or mips), or a mixture: in IEEE 754 128-bit double
7045 * or in a double-double, the first half of the payload can follow the
7046 * native double, while in the second half the payload can be all
7047 * zeros. (Therefore the mask for payload bits is not necessarily
7048 * identical to bit complement of the NaN.) Another way of putting
7049 * this: the payload for the default NaN might not be zero.
7051 * For the x86 80-bit long doubles, the trailing bytes (the 80 bits
7052 * being 'packaged' in either 12 or 16 bytes) can be whatever random
7055 * Furthermore, the semantics of the sign bit on NaNs are platform-specific.
7056 * On normal floats, the sign bit being on means negative. But this may,
7057 * or may not, be reverted on NaNs: in other words, the default NaN might
7058 * have the sign bit on, and therefore look like negative if you look
7059 * at it at the bit level.
7061 * NaN payloads are not propagated even on copies, or in arithmetics.
7062 * They *might* be, according to some rules, on your particular
7063 * cpu/os/compiler/libraries, but no guarantees.
7065 * To summarize, on most platforms, and for 64-bit doubles
7066 * (using big-endian ordering here):
7068 * [7FF8000000000000..7FFFFFFFFFFFFFFF] quiet
7069 * [FFF8000000000000..FFFFFFFFFFFFFFFF] quiet
7070 * [7FF0000000000001..7FF7FFFFFFFFFFFF] signaling
7071 * [FFF0000000000001..FFF7FFFFFFFFFFFF] signaling
7073 * The C99 nan() is supposed to generate *quiet* NaNs.
7075 * Note the asymmetry:
7076 * The 7FF0000000000000 is positive infinity,
7077 * the FFF0000000000000 is negative infinity.
7080 /* NVMANTBITS is the number of _real_ mantissa bits in an NV.
7081 * For the standard IEEE 754 fp this number is usually one less that
7082 * *DBL_MANT_DIG because of the implicit (aka hidden) bit, which isn't
7083 * real. For the 80-bit extended precision formats (x86*), the number
7084 * of mantissa bits... depends. For normal floats, it's 64. But for
