5822 This macro should be used as a statement. It declares a private variable
5823 (whose name begins with an underscore) that is needed by the other macros in
5824 this section. Failing to include this correctly should lead to a syntax error.
5825 For compatibility with C89 C compilers it should be placed in a block before
5826 any executable statements.
5828 =for apidoc Am|void|STORE_LC_NUMERIC_FORCE_TO_UNDERLYING
5830 This is used by XS code that that is C<LC_NUMERIC> locale-aware to force the
5831 locale for category C<LC_NUMERIC> to be what perl thinks is the current
5832 underlying locale. (The perl interpreter could be wrong about what the
5833 underlying locale actually is if some C or XS code has called the C library
5834 function L<setlocale(3)> behind its back; calling L</sync_locale> before calling
5835 this macro will update perl's records.)
5837 A call to L</DECLARATION_FOR_LC_NUMERIC_MANIPULATION> must have been made to
5838 declare at compile time a private variable used by this macro. This macro
5839 should be called as a single statement, not an expression, but with an empty
5840 argument list, like this:
5843 DECLARATION_FOR_LC_NUMERIC_MANIPULATION;
5845 STORE_LC_NUMERIC_FORCE_TO_UNDERLYING();
5847 RESTORE_LC_NUMERIC();
5851 The private variable is used to save the current locale state, so
5852 that the requisite matching call to L</RESTORE_LC_NUMERIC> can restore it.
5854 On threaded perls not operating with thread-safe functionality, this macro uses
5855 a mutex to force a critical section. Therefore the matching RESTORE should be
5856 close by, and guaranteed to be called.
5858 =for apidoc Am|void|STORE_LC_NUMERIC_SET_TO_NEEDED
5860 This is used to help wrap XS or C code that is C<LC_NUMERIC> locale-aware.
5861 This locale category is generally kept set to a locale where the decimal radix
5862 character is a dot, and the separator between groups of digits is empty. This
5863 is because most XS code that reads floating point numbers is expecting them to
5866 This macro makes sure the current C<LC_NUMERIC> state is set properly, to be
5867 aware of locale if the call to the XS or C code from the Perl program is
5868 from within the scope of a S<C<use locale>>; or to ignore locale if the call is
5869 instead from outside such scope.
5871 This macro is the start of wrapping the C or XS code; the wrap ending is done
5872 by calling the L</RESTORE_LC_NUMERIC> macro after the operation. Otherwise
5873 the state can be changed that will adversely affect other XS code.
5875 A call to L</DECLARATION_FOR_LC_NUMERIC_MANIPULATION> must have been made to
5876 declare at compile time a private variable used by this macro. This macro
5877 should be called as a single statement, not an expression, but with an empty
5878 argument list, like this:
5881 DECLARATION_FOR_LC_NUMERIC_MANIPULATION;
5883 STORE_LC_NUMERIC_SET_TO_NEEDED();
5885 RESTORE_LC_NUMERIC();
5889 On threaded perls not operating with thread-safe functionality, this macro uses
5890 a mutex to force a critical section. Therefore the matching RESTORE should be
5891 close by, and guaranteed to be called.
5893 =for apidoc Am|void|RESTORE_LC_NUMERIC
5895 This is used in conjunction with one of the macros
5896 L</STORE_LC_NUMERIC_SET_TO_NEEDED>
5897 and L</STORE_LC_NUMERIC_FORCE_TO_UNDERLYING> to properly restore the
5898 C<LC_NUMERIC> state.
5900 A call to L</DECLARATION_FOR_LC_NUMERIC_MANIPULATION> must have been made to
5901 declare at compile time a private variable used by this macro and the two
5902 C<STORE> ones. This macro should be called as a single statement, not an
5903 expression, but with an empty argument list, like this:

6864 * for the nan payload.
6866 * Note that the 32-bit x86 ABI cannot do signaling nans: the x87
6867 * simply cannot preserve the bit. You can either use the 80-bit
6868 * extended precision (long double, -Duselongdouble), or use x86-64.
6870 * In all platforms, the payload bytes (and bits, some of them are
6871 * often in a partial byte) themselves can be either all zero (x86),
6872 * all one (sparc or mips), or a mixture: in IEEE 754 128-bit double
6873 * or in a double-double, the first half of the payload can follow the
6874 * native double, while in the second half the payload can be all
6875 * zeros. (Therefore the mask for payload bits is not necessarily
6876 * identical to bit complement of the NaN.) Another way of putting
6877 * this: the payload for the default NaN might not be zero.
6879 * For the x86 80-bit long doubles, the trailing bytes (the 80 bits
6880 * being 'packaged' in either 12 or 16 bytes) can be whatever random
6883 * Furthermore, the semantics of the sign bit on NaNs are platform-specific.
6884 * On normal floats, the sign bit being on means negative. But this may,
6885 * or may not, be reverted on NaNs: in other words, the default NaN might
6886 * have the sign bit on, and therefore look like negative if you look
6887 * at it at the bit level.
6889 * NaN payloads are not propagated even on copies, or in arithmetics.
6890 * They *might* be, according to some rules, on your particular
6891 * cpu/os/compiler/libraries, but no guarantees.
6893 * To summarize, on most platforms, and for 64-bit doubles
6894 * (using big-endian ordering here):
6896 * [7FF8000000000000..7FFFFFFFFFFFFFFF] quiet
6897 * [FFF8000000000000..FFFFFFFFFFFFFFFF] quiet
6898 * [7FF0000000000001..7FF7FFFFFFFFFFFF] signaling
6899 * [FFF0000000000001..FFF7FFFFFFFFFFFF] signaling
6901 * The C99 nan() is supposed to generate *quiet* NaNs.
6903 * Note the asymmetry:
6904 * The 7FF0000000000000 is positive infinity,
6905 * the FFF0000000000000 is negative infinity.
6908 /* NVMANTBITS is the number of _real_ mantissa bits in an NV.
6909 * For the standard IEEE 754 fp this number is usually one less that
6910 * *DBL_MANT_DIG because of the implicit (aka hidden) bit, which isn't
6911 * real. For the 80-bit extended precision formats (x86*), the number
6912 * of mantissa bits... depends. For normal floats, it's 64. But for
6913 * the inf/nan, it's different (zero for inf, 61 for nan).
6914 * NVMANTBITS works for normal floats. */
