5683 This macro should be used as a statement. It declares a private variable
5684 (whose name begins with an underscore) that is needed by the other macros in
5685 this section. Failing to include this correctly should lead to a syntax error.
5686 For compatibility with C89 C compilers it should be placed in a block before
5687 any executable statements.
5689 =for apidoc Am|void|STORE_LC_NUMERIC_FORCE_TO_UNDERLYING
5691 This is used by XS code that that is C<LC_NUMERIC> locale-aware to force the
5692 locale for category C<LC_NUMERIC> to be what perl thinks is the current
5693 underlying locale. (The perl interpreter could be wrong about what the
5694 underlying locale actually is if some C or XS code has called the C library
5695 function L<setlocale(3)> behind its back; calling L</sync_locale> before calling
5696 this macro will update perl's records.)
5698 A call to L</DECLARATION_FOR_LC_NUMERIC_MANIPULATION> must have been made to
5699 declare at compile time a private variable used by this macro. This macro
5700 should be called as a single statement, not an expression, but with an empty
5701 argument list, like this:
5704 DECLARATION_FOR_LC_NUMERIC_MANIPULATION;
5706 STORE_LC_NUMERIC_FORCE_TO_UNDERLYING();
5708 RESTORE_LC_NUMERIC();
5712 The private variable is used to save the current locale state, so
5713 that the requisite matching call to L</RESTORE_LC_NUMERIC> can restore it.
5715 =for apidoc Am|void|STORE_LC_NUMERIC_SET_TO_NEEDED
5717 This is used to help wrap XS or C code that that is C<LC_NUMERIC> locale-aware.
5718 This locale category is generally kept set to the C locale by Perl for
5719 backwards compatibility, and because most XS code that reads floating point
5720 values can cope only with the decimal radix character being a dot.
5722 This macro makes sure the current C<LC_NUMERIC> state is set properly, to be
5723 aware of locale if the call to the XS or C code from the Perl program is
5724 from within the scope of a S<C<use locale>>; or to ignore locale if the call is
5725 instead from outside such scope.
5727 This macro is the start of wrapping the C or XS code; the wrap ending is done
5728 by calling the L</RESTORE_LC_NUMERIC> macro after the operation. Otherwise
5729 the state can be changed that will adversely affect other XS code.
5731 A call to L</DECLARATION_FOR_LC_NUMERIC_MANIPULATION> must have been made to
5732 declare at compile time a private variable used by this macro. This macro
5733 should be called as a single statement, not an expression, but with an empty
5734 argument list, like this:
5737 DECLARATION_FOR_LC_NUMERIC_MANIPULATION;
5739 STORE_LC_NUMERIC_SET_TO_NEEDED();
5741 RESTORE_LC_NUMERIC();
5745 =for apidoc Am|void|RESTORE_LC_NUMERIC
5747 This is used in conjunction with one of the macros
5748 L</STORE_LC_NUMERIC_SET_TO_NEEDED>
5749 and L</STORE_LC_NUMERIC_FORCE_TO_UNDERLYING> to properly restore the
5750 C<LC_NUMERIC> state.
5752 A call to L</DECLARATION_FOR_LC_NUMERIC_MANIPULATION> must have been made to
5753 declare at compile time a private variable used by this macro and the two
5754 C<STORE> ones. This macro should be called as a single statement, not an
5755 expression, but with an empty argument list, like this:
5758 DECLARATION_FOR_LC_NUMERIC_MANIPULATION;
5760 RESTORE_LC_NUMERIC();

5771 * The other is non-zero if the current locale is the underlying locale. Both
5772 * can be non-zero if, as often happens, the underlying locale is C.
5774 * Its slightly more complicated than this, as the PL_numeric_standard variable

6637 * To back up a bit (harhar):
6639 * For IEEE 754 64-bit formats [1]:
6641 * s 000 (mantissa all-zero) zero
6642 * s 000 (mantissa non-zero) subnormals (denormals)
6643 * s 001 ... 7fe normals
6646 * For IEEE 754 128-bit formats:
6648 * s 0000 (mantissa all-zero) zero
6649 * s 0000 (mantissa non-zero) subnormals (denormals)
6650 * s 0001 ... 7ffe normals
6653 * [1] this looks like big-endian, but applies equally to little-endian.
6655 * s = Sign bit. Yes, zeros and nans can have negative sign,
6656 * the interpretation is application-specific.
6658 * q = Quietness bit, the interpretation is platform-specific.
6659 * Most platforms have the most significant bit being one
6660 * meaning quiet, but some (older mips, hppa) have the msb
6661 * being one meaning signaling. Note that the above means
6662 * that on most platforms there cannot be signaling nan with
6663 * zero payload because that is identical with infinity;
6664 * while conversely on older mips/hppa there cannot be a quiet nan
6665 * because that is identical with infinity.
6667 * Moreover, whether there is any behavioral difference
6668 * between quiet and signaling NaNs, depends on the platform.
6670 * x86 80-bit extended precision is different, the mantissa bits:
6672 * 63 62 61 30387+ pre-387 visual c
6673 * -------- ---- -------- --------
6674 * 0 0 0 invalid infinity
6675 * 0 0 1 invalid snan
6676 * 0 1 0 invalid snan
6677 * 0 1 1 invalid snan
6678 * 1 0 0 infinity snan 1.#INF
6679 * 1 0 1 snan 1.#SNAN
6680 * 1 1 0 qnan -1.#IND (x86 chooses this to negative)
6681 * 1 1 1 qnan 1.#QNAN
6683 * This means that in this format there are 61 bits available
6684 * for the nan payload.
6686 * Note that the 32-bit x86 ABI cannot do signaling nans: the x87
6687 * simply cannot preserve the bit. You can either use the 80-bit
6688 * extended precision (long double, -Duselongdouble), or use x86-64.
6690 * In all platforms, the payload bytes (and bits, some of them are
6691 * often in a partial byte) themselves can be either all zero (x86),
6692 * all one (sparc or mips), or a mixture: in IEEE 754 128-bit double
6693 * or in a double-double, the first half of the payload can follow the
6694 * native double, while in the second half the payload can be all
6695 * zeros. (Therefore the mask for payload bits is not necessarily
6696 * identical to bit complement of the NaN.) Another way of putting
6697 * this: the payload for the default NaN might not be zero.
6699 * For the x86 80-bit long doubles, the trailing bytes (the 80 bits
6700 * being 'packaged' in either 12 or 16 bytes) can be whatever random
6703 * Furthermore, the semantics of the sign bit on NaNs are platform-specific.
6704 * On normal floats, the sign bit being on means negative. But this may,
6705 * or may not, be reverted on NaNs: in other words, the default NaN might
6706 * have the sign bit on, and therefore look like negative if you look
6707 * at it at the bit level.
6709 * NaN payloads are not propagated even on copies, or in arithmetics.
6710 * They *might* be, according to some rules, on your particular
6711 * cpu/os/compiler/libraries, but no guarantees.
6713 * To summarize, on most platforms, and for 64-bit doubles
6714 * (using big-endian ordering here):
6716 * [7FF8000000000000..7FFFFFFFFFFFFFFF] quiet
6717 * [FFF8000000000000..FFFFFFFFFFFFFFFF] quiet
6718 * [7FF0000000000001..7FF7FFFFFFFFFFFF] signaling
6719 * [FFF0000000000001..FFF7FFFFFFFFFFFF] signaling
6721 * The C99 nan() is supposed to generate *quiet* NaNs.
6723 * Note the asymmetry:
6724 * The 7FF0000000000000 is positive infinity,
6725 * the FFF0000000000000 is negative infinity.
6728 /* NVMANTBITS is the number of _real_ mantissa bits in an NV.
6729 * For the standard IEEE 754 fp this number is usually one less that
6730 * *DBL_MANT_DIG because of the implicit (aka hidden) bit, which isn't
6731 * real. For the 80-bit extended precision formats (x86*), the number
6732 * of mantissa bits... depends. For normal floats, it's 64. But for
