5879=head1 Locale-related functions and macros
5880
5881=for apidoc Amn|void|DECLARATION_FOR_LC_NUMERIC_MANIPULATION
5882
5883This macro should be used as a statement. It declares a private variable
5884(whose name begins with an underscore) that is needed by the other macros in
5885this section. Failing to include this correctly should lead to a syntax error.
5886For compatibility with C89 C compilers it should be placed in a block before
5887any executable statements.
5888
5889=for apidoc Am|void|STORE_LC_NUMERIC_FORCE_TO_UNDERLYING
5890
5891This is used by XS code that that is C<LC_NUMERIC> locale-aware to force the
5892locale for category C<LC_NUMERIC> to be what perl thinks is the current
5893underlying locale. (The perl interpreter could be wrong about what the
5894underlying locale actually is if some C or XS code has called the C library
5895function L<setlocale(3)> behind its back; calling L</sync_locale> before calling
5896this macro will update perl's records.)
5897
5898A call to L</DECLARATION_FOR_LC_NUMERIC_MANIPULATION> must have been made to
5899declare at compile time a private variable used by this macro. This macro
5900should be called as a single statement, not an expression, but with an empty
5901argument list, like this:
5902
5903 {
5904 DECLARATION_FOR_LC_NUMERIC_MANIPULATION;
5905 ...
5906 STORE_LC_NUMERIC_FORCE_TO_UNDERLYING();
5907 ...
5908 RESTORE_LC_NUMERIC();
5909 ...
5910 }
5911
5912The private variable is used to save the current locale state, so
5913that the requisite matching call to L</RESTORE_LC_NUMERIC> can restore it.
5914
5915=for apidoc Am|void|STORE_LC_NUMERIC_SET_TO_NEEDED
5916
5917This is used to help wrap XS or C code that that is C<LC_NUMERIC> locale-aware.
5918This locale category is generally kept set to the C locale by Perl for
5919backwards compatibility, and because most XS code that reads floating point
5920values can cope only with the decimal radix character being a dot.
5921
5922This macro makes sure the current C<LC_NUMERIC> state is set properly, to be
5923aware of locale if the call to the XS or C code from the Perl program is
5924from within the scope of a S<C<use locale>>; or to ignore locale if the call is
5925instead from outside such scope.
5926
5927This macro is the start of wrapping the C or XS code; the wrap ending is done
5928by calling the L</RESTORE_LC_NUMERIC> macro after the operation. Otherwise
5929the state can be changed that will adversely affect other XS code.
5930
5931A call to L</DECLARATION_FOR_LC_NUMERIC_MANIPULATION> must have been made to
5932declare at compile time a private variable used by this macro. This macro
5933should be called as a single statement, not an expression, but with an empty
5934argument list, like this:
5935
5936 {
5937 DECLARATION_FOR_LC_NUMERIC_MANIPULATION;
5938 ...
5939 STORE_LC_NUMERIC_SET_TO_NEEDED();
5940 ...
5941 RESTORE_LC_NUMERIC();
5942 ...
5943 }
5944
5945=for apidoc Am|void|RESTORE_LC_NUMERIC
5946
5947This is used in conjunction with one of the macros
5948L</STORE_LC_NUMERIC_SET_TO_NEEDED>
5949and
5950L</STORE_LC_NUMERIC_FORCE_TO_UNDERLYING>
5951
5952to properly restore the C<LC_NUMERIC> state.
5953
5954A call to L</DECLARATION_FOR_LC_NUMERIC_MANIPULATION> must have been made to
5955declare at compile time a private variable used by this macro and the two
5956C<STORE> ones. This macro should be called as a single statement, not an
5957expression, but with an empty argument list, like this:
5958
5959 {
5960 DECLARATION_FOR_LC_NUMERIC_MANIPULATION;
5961 ...
5962 RESTORE_LC_NUMERIC();

JH		 6625/* NaNs (not-a-numbers) can carry payload bits, in addition to
6626 * "nan-ness". Part of the payload is the quiet/signaling bit.
6627 * To back up a bit (harhar):
6628 *
6629 * For IEEE 754 64-bit formats [1]:
6630 *
6631 * s 000 (mantissa all-zero) zero
6632 * s 000 (mantissa non-zero) subnormals (denormals)
6633 * s 001 ... 7fe normals
6634 * s 7ff q nan
6635 *
6636 * For IEEE 754 128-bit formats:
6637 *
6638 * s 0000 (mantissa all-zero) zero
6639 * s 0000 (mantissa non-zero) subnormals (denormals)
6640 * s 0001 ... 7ffe normals
6641 * s 7fff q nan
6642 *
6643 * [1] this looks like big-endian, but applies equally to little-endian.
6644 *
6645 * s = Sign bit. Yes, zeros and nans can have negative sign,
6646 * the interpretation is application-specific.
6647 *
6648 * q = Quietness bit, the interpretation is platform-specific.
453b60f1 6649 * Most platforms have the most significant bit being one
5c255b3b
JH		 6650 * meaning quiet, but some (older mips, hppa) have the msb
6651 * being one meaning signaling. Note that the above means
6652 * that on most platforms there cannot be signaling nan with
453b60f1
JH		 6653 * zero payload because that is identical with infinity;
6654 * while conversely on older mips/hppa there cannot be a quiet nan
6655 * because that is identical with infinity.
6656 *
6657 * Moreover, whether there is any behavioral difference
6658 * between quiet and signaling NaNs, depends on the platform.
5c255b3b
JH		 6659 *
6660 * x86 80-bit extended precision is different, the mantissa bits:
6661 *
6662 * 63 62 61 30387+ pre-387 visual c
6663 * -------- ---- -------- --------
6664 * 0 0 0 invalid infinity
6665 * 0 0 1 invalid snan
6666 * 0 1 0 invalid snan
6667 * 0 1 1 invalid snan
6668 * 1 0 0 infinity snan 1.#INF
6669 * 1 0 1 snan 1.#SNAN
6670 * 1 1 0 qnan -1.#IND (x86 chooses this to negative)
6671 * 1 1 1 qnan 1.#QNAN
6672 *
6673 * This means that in this format there are 61 bits available
6674 * for the nan payload.
6675 *
453b60f1
JH		 6676 * In all platforms, the payload bytes (and bits, some of them are
6677 * often in a partial byte) themselves can be either all zero (x86),
6678 * all one (sparc or mips), or a mixture: in IEEE 754 128-bit double
6679 * or in a double-double, the first half of the payload can follow the
6680 * native double, while in the second half the payload can be all
6681 * zeros. (Therefore the mask for payload bits is not necessarily
6682 * identical to bit complement of the NaN.) Another way of putting
6683 * this: the payload for the default NaN might not be zero.
6684 *
6685 * For the x86 80-bit long doubles, the trailing bytes (the 80 bits
6686 * being 'packaged' in either 12 or 16 bytes) can be whatever random
6687 * garbage.
6688 *
6689 * Furthermore, the semantics of the sign bit on NaNs are platform-specific.
6690 * On normal floats, the sign bit being on means negative. But this may,
6691 * or may not, be reverted on NaNs: in other words, the default NaN might
6692 * have the sign bit on, and therefore look like negative if you look
6693 * at it at the bit level.
6694 *
6695 * NaN payloads are not propagated even on copies, or in arithmetics.
6696 * They *might* be, according to some rules, on your particular
6697 * cpu/os/compiler/libraries, but no guarantees.
6698 *
6699 * To summarize, on most platforms, and for 64-bit doubles
6700 * (using big-endian ordering here):
6701 *
6702 * [7FF8000000000000..7FFFFFFFFFFFFFFF] quiet
6703 * [FFF8000000000000..FFFFFFFFFFFFFFFF] quiet
6704 * [7FF0000000000001..7FF7FFFFFFFFFFFF] signaling
6705 * [FFF0000000000001..FFF7FFFFFFFFFFFF] signaling
6706 *
6707 * The C99 nan() is supposed to generate *quiet* NaNs.
6708 *
6709 * Note the asymmetry:
6710 * The 7FF0000000000000 is positive infinity,
6711 * the FFF0000000000000 is negative infinity.
