5892 This macro should be used as a statement. It declares a private variable
5893 (whose name begins with an underscore) that is needed by the other macros in
5894 this section. Failing to include this correctly should lead to a syntax error.
5895 For compatibility with C89 C compilers it should be placed in a block before
5896 any executable statements.
5898 =for apidoc Am|void|STORE_LC_NUMERIC_FORCE_TO_UNDERLYING
5900 This is used by XS code that that is C<LC_NUMERIC> locale-aware to force the
5901 locale for category C<LC_NUMERIC> to be what perl thinks is the current
5902 underlying locale. (The perl interpreter could be wrong about what the
5903 underlying locale actually is if some C or XS code has called the C library
5904 function L<setlocale(3)> behind its back; calling L</sync_locale> before calling
5905 this macro will update perl's records.)
5907 A call to L</DECLARATION_FOR_LC_NUMERIC_MANIPULATION> must have been made to
5908 declare at compile time a private variable used by this macro. This macro
5909 should be called as a single statement, not an expression, but with an empty
5910 argument list, like this:
5913 DECLARATION_FOR_LC_NUMERIC_MANIPULATION;
5915 STORE_LC_NUMERIC_FORCE_TO_UNDERLYING();
5917 RESTORE_LC_NUMERIC();
5921 The private variable is used to save the current locale state, so
5922 that the requisite matching call to L</RESTORE_LC_NUMERIC> can restore it.
5924 =for apidoc Am|void|STORE_LC_NUMERIC_SET_TO_NEEDED
5926 This is used to help wrap XS or C code that that is C<LC_NUMERIC> locale-aware.
5927 This locale category is generally kept set to the C locale by Perl for
5928 backwards compatibility, and because most XS code that reads floating point
5929 values can cope only with the decimal radix character being a dot.
5931 This macro makes sure the current C<LC_NUMERIC> state is set properly, to be
5932 aware of locale if the call to the XS or C code from the Perl program is
5933 from within the scope of a S<C<use locale>>; or to ignore locale if the call is
5934 instead from outside such scope.
5936 This macro is the start of wrapping the C or XS code; the wrap ending is done
5937 by calling the L</RESTORE_LC_NUMERIC> macro after the operation. Otherwise
5938 the state can be changed that will adversely affect other XS code.
5940 A call to L</DECLARATION_FOR_LC_NUMERIC_MANIPULATION> must have been made to
5941 declare at compile time a private variable used by this macro. This macro
5942 should be called as a single statement, not an expression, but with an empty
5943 argument list, like this:
5946 DECLARATION_FOR_LC_NUMERIC_MANIPULATION;
5948 STORE_LC_NUMERIC_SET_TO_NEEDED();
5950 RESTORE_LC_NUMERIC();

5957 L</STORE_LC_NUMERIC_SET_TO_NEEDED>
5959 L</STORE_LC_NUMERIC_FORCE_TO_UNDERLYING>
5961 to properly restore the C<LC_NUMERIC> state.
5963 A call to L</DECLARATION_FOR_LC_NUMERIC_MANIPULATION> must have been made to
5964 declare at compile time a private variable used by this macro and the two
5965 C<STORE> ones. This macro should be called as a single statement, not an
5966 expression, but with an empty argument list, like this:

6634 /* NaNs (not-a-numbers) can carry payload bits, in addition to
6635 * "nan-ness". Part of the payload is the quiet/signaling bit.
6636 * To back up a bit (harhar):
6638 * For IEEE 754 64-bit formats [1]:
6640 * s 000 (mantissa all-zero) zero
6641 * s 000 (mantissa non-zero) subnormals (denormals)
6642 * s 001 ... 7fe normals
6645 * For IEEE 754 128-bit formats:
6647 * s 0000 (mantissa all-zero) zero
6648 * s 0000 (mantissa non-zero) subnormals (denormals)
6649 * s 0001 ... 7ffe normals
6652 * [1] this looks like big-endian, but applies equally to little-endian.
6654 * s = Sign bit. Yes, zeros and nans can have negative sign,
6655 * the interpretation is application-specific.
6657 * q = Quietness bit, the interpretation is platform-specific.
6658 * Most platforms have the most significant bit being one
6659 * meaning quiet, but some (older mips, hppa) have the msb
6660 * being one meaning signaling. Note that the above means
6661 * that on most platforms there cannot be signaling nan with
6662 * zero payload because that is identical with infinity;
6663 * while conversely on older mips/hppa there cannot be a quiet nan
6664 * because that is identical with infinity.
6666 * Moreover, whether there is any behavioral difference
6667 * between quiet and signaling NaNs, depends on the platform.
6669 * x86 80-bit extended precision is different, the mantissa bits:
6671 * 63 62 61 30387+ pre-387 visual c
6672 * -------- ---- -------- --------
6673 * 0 0 0 invalid infinity
6674 * 0 0 1 invalid snan
6675 * 0 1 0 invalid snan
6676 * 0 1 1 invalid snan
6677 * 1 0 0 infinity snan 1.#INF
6678 * 1 0 1 snan 1.#SNAN
6679 * 1 1 0 qnan -1.#IND (x86 chooses this to negative)
6680 * 1 1 1 qnan 1.#QNAN
6682 * This means that in this format there are 61 bits available
6683 * for the nan payload.
6685 * Note that the 32-bit x86 ABI cannot do signaling nans: the x87
6686 * simply cannot preserve the bit. You can either use the 80-bit
6687 * extended precision (long double, -Duselongdouble), or use x86-64.
6689 * In all platforms, the payload bytes (and bits, some of them are
6690 * often in a partial byte) themselves can be either all zero (x86),
6691 * all one (sparc or mips), or a mixture: in IEEE 754 128-bit double
6692 * or in a double-double, the first half of the payload can follow the
6693 * native double, while in the second half the payload can be all
6694 * zeros. (Therefore the mask for payload bits is not necessarily
6695 * identical to bit complement of the NaN.) Another way of putting
6696 * this: the payload for the default NaN might not be zero.
6698 * For the x86 80-bit long doubles, the trailing bytes (the 80 bits
6699 * being 'packaged' in either 12 or 16 bytes) can be whatever random
6702 * Furthermore, the semantics of the sign bit on NaNs are platform-specific.
6703 * On normal floats, the sign bit being on means negative. But this may,
6704 * or may not, be reverted on NaNs: in other words, the default NaN might
6705 * have the sign bit on, and therefore look like negative if you look
6706 * at it at the bit level.
6708 * NaN payloads are not propagated even on copies, or in arithmetics.
6709 * They *might* be, according to some rules, on your particular
6710 * cpu/os/compiler/libraries, but no guarantees.
6712 * To summarize, on most platforms, and for 64-bit doubles
6713 * (using big-endian ordering here):
6715 * [7FF8000000000000..7FFFFFFFFFFFFFFF] quiet
6716 * [FFF8000000000000..FFFFFFFFFFFFFFFF] quiet
6717 * [7FF0000000000001..7FF7FFFFFFFFFFFF] signaling
6718 * [FFF0000000000001..FFF7FFFFFFFFFFFF] signaling
6720 * The C99 nan() is supposed to generate *quiet* NaNs.
6722 * Note the asymmetry:
6723 * The 7FF0000000000000 is positive infinity,
6724 * the FFF0000000000000 is negative infinity.
6727 /* NVMANTBITS is the number of _real_ mantissa bits in an NV.
6728 * For the standard IEEE 754 fp this number is usually one less that
6729 * *DBL_MANT_DIG because of the implicit (aka hidden) bit, which isn't
6730 * real. For the 80-bit extended precision formats (x86*), the number
6731 * of mantissa bits... depends. For normal floats, it's 64. But for
6732 * the inf/nan, it's different (zero for inf, 61 for nan).
6733 * NVMANTBITS works for normal floats. */
