5819 This macro should be used as a statement. It declares a private variable
5820 (whose name begins with an underscore) that is needed by the other macros in
5821 this section. Failing to include this correctly should lead to a syntax error.
5822 For compatibility with C89 C compilers it should be placed in a block before
5823 any executable statements.
5825 =for apidoc Am|void|STORE_LC_NUMERIC_FORCE_TO_UNDERLYING
5827 This is used by XS code that that is C<LC_NUMERIC> locale-aware to force the
5828 locale for category C<LC_NUMERIC> to be what perl thinks is the current
5829 underlying locale. (The perl interpreter could be wrong about what the
5830 underlying locale actually is if some C or XS code has called the C library
5831 function L<setlocale(3)> behind its back; calling L</sync_locale> before calling
5832 this macro will update perl's records.)
5834 A call to L</DECLARATION_FOR_LC_NUMERIC_MANIPULATION> must have been made to
5835 declare at compile time a private variable used by this macro. This macro
5836 should be called as a single statement, not an expression, but with an empty
5837 argument list, like this:
5840 DECLARATION_FOR_LC_NUMERIC_MANIPULATION;
5842 STORE_LC_NUMERIC_FORCE_TO_UNDERLYING();
5844 RESTORE_LC_NUMERIC();
5848 The private variable is used to save the current locale state, so
5849 that the requisite matching call to L</RESTORE_LC_NUMERIC> can restore it.
5851 On threaded perls not operating with thread-safe functionality, this macro uses
5852 a mutex to force a critical section. Therefore the matching RESTORE should be
5853 close by, and guaranteed to be called.
5855 =for apidoc Am|void|STORE_LC_NUMERIC_SET_TO_NEEDED
5857 This is used to help wrap XS or C code that is C<LC_NUMERIC> locale-aware.
5858 This locale category is generally kept set to a locale where the decimal radix
5859 character is a dot, and the separator between groups of digits is empty. This
5860 is because most XS code that reads floating point numbers is expecting them to
5863 This macro makes sure the current C<LC_NUMERIC> state is set properly, to be
5864 aware of locale if the call to the XS or C code from the Perl program is
5865 from within the scope of a S<C<use locale>>; or to ignore locale if the call is
5866 instead from outside such scope.
5868 This macro is the start of wrapping the C or XS code; the wrap ending is done
5869 by calling the L</RESTORE_LC_NUMERIC> macro after the operation. Otherwise
5870 the state can be changed that will adversely affect other XS code.
5872 A call to L</DECLARATION_FOR_LC_NUMERIC_MANIPULATION> must have been made to
5873 declare at compile time a private variable used by this macro. This macro
5874 should be called as a single statement, not an expression, but with an empty
5875 argument list, like this:
5878 DECLARATION_FOR_LC_NUMERIC_MANIPULATION;
5880 STORE_LC_NUMERIC_SET_TO_NEEDED();
5882 RESTORE_LC_NUMERIC();

5887 a mutex to force a critical section. Therefore the matching RESTORE should be
5888 close by, and guaranteed to be called.

5892 This is used in conjunction with one of the macros
5893 L</STORE_LC_NUMERIC_SET_TO_NEEDED>
5894 and L</STORE_LC_NUMERIC_FORCE_TO_UNDERLYING> to properly restore the
5895 C<LC_NUMERIC> state.
5897 A call to L</DECLARATION_FOR_LC_NUMERIC_MANIPULATION> must have been made to
5898 declare at compile time a private variable used by this macro and the two
5899 C<STORE> ones. This macro should be called as a single statement, not an

6857 * 1 1 0 qnan -1.#IND (x86 chooses this to negative)
6858 * 1 1 1 qnan 1.#QNAN
6860 * This means that in this format there are 61 bits available
6861 * for the nan payload.
6863 * Note that the 32-bit x86 ABI cannot do signaling nans: the x87
6864 * simply cannot preserve the bit. You can either use the 80-bit
6865 * extended precision (long double, -Duselongdouble), or use x86-64.
6867 * In all platforms, the payload bytes (and bits, some of them are
6868 * often in a partial byte) themselves can be either all zero (x86),
6869 * all one (sparc or mips), or a mixture: in IEEE 754 128-bit double
6870 * or in a double-double, the first half of the payload can follow the
6871 * native double, while in the second half the payload can be all
6872 * zeros. (Therefore the mask for payload bits is not necessarily
6873 * identical to bit complement of the NaN.) Another way of putting
6874 * this: the payload for the default NaN might not be zero.
6876 * For the x86 80-bit long doubles, the trailing bytes (the 80 bits
6877 * being 'packaged' in either 12 or 16 bytes) can be whatever random
6880 * Furthermore, the semantics of the sign bit on NaNs are platform-specific.
6881 * On normal floats, the sign bit being on means negative. But this may,
6882 * or may not, be reverted on NaNs: in other words, the default NaN might
6883 * have the sign bit on, and therefore look like negative if you look
6884 * at it at the bit level.
6886 * NaN payloads are not propagated even on copies, or in arithmetics.
6887 * They *might* be, according to some rules, on your particular
6888 * cpu/os/compiler/libraries, but no guarantees.
6890 * To summarize, on most platforms, and for 64-bit doubles
6891 * (using big-endian ordering here):
6893 * [7FF8000000000000..7FFFFFFFFFFFFFFF] quiet
6894 * [FFF8000000000000..FFFFFFFFFFFFFFFF] quiet
6895 * [7FF0000000000001..7FF7FFFFFFFFFFFF] signaling
6896 * [FFF0000000000001..FFF7FFFFFFFFFFFF] signaling
6898 * The C99 nan() is supposed to generate *quiet* NaNs.
6900 * Note the asymmetry:
6901 * The 7FF0000000000000 is positive infinity,
6902 * the FFF0000000000000 is negative infinity.
6905 /* NVMANTBITS is the number of _real_ mantissa bits in an NV.
6906 * For the standard IEEE 754 fp this number is usually one less that
6907 * *DBL_MANT_DIG because of the implicit (aka hidden) bit, which isn't
6908 * real. For the 80-bit extended precision formats (x86*), the number
6909 * of mantissa bits... depends. For normal floats, it's 64. But for
6910 * the inf/nan, it's different (zero for inf, 61 for nan).
6911 * NVMANTBITS works for normal floats. */
