| 5945 | |
| 5946 | This macro should be used as a statement. It declares a private variable |
| 5947 | (whose name begins with an underscore) that is needed by the other macros in |
| 5948 | this section. Failing to include this correctly should lead to a syntax error. |
| 5949 | For compatibility with C89 C compilers it should be placed in a block before |
| 5950 | any executable statements. |
| 5951 | |
| 5952 | =for apidoc Am|void|STORE_LC_NUMERIC_FORCE_TO_UNDERLYING |
| 5953 | |
| 5954 | This is used by XS code that that is C<LC_NUMERIC> locale-aware to force the |
| 5955 | locale for category C<LC_NUMERIC> to be what perl thinks is the current |
| 5956 | underlying locale. (The perl interpreter could be wrong about what the |
| 5957 | underlying locale actually is if some C or XS code has called the C library |
| 5958 | function L<setlocale(3)> behind its back; calling L</sync_locale> before calling |
| 5959 | this macro will update perl's records.) |
| 5960 | |
| 5961 | A call to L</DECLARATION_FOR_LC_NUMERIC_MANIPULATION> must have been made to |
| 5962 | declare at compile time a private variable used by this macro. This macro |
| 5963 | should be called as a single statement, not an expression, but with an empty |
| 5964 | argument list, like this: |
| 5965 | |
| 5966 | { |
| 5967 | DECLARATION_FOR_LC_NUMERIC_MANIPULATION; |
| 5968 | ... |
| 5969 | STORE_LC_NUMERIC_FORCE_TO_UNDERLYING(); |
| 5970 | ... |
| 5971 | RESTORE_LC_NUMERIC(); |
| 5972 | ... |
| 5973 | } |
| 5974 | |
| 5975 | The private variable is used to save the current locale state, so |
| 5976 | that the requisite matching call to L</RESTORE_LC_NUMERIC> can restore it. |
| 5977 | |
| 5978 | =for apidoc Am|void|STORE_LC_NUMERIC_SET_TO_NEEDED |
| 5979 | |
| 5980 | This is used to help wrap XS or C code that that is C<LC_NUMERIC> locale-aware. |
| 5981 | This locale category is generally kept set to the C locale by Perl for |
| 5982 | backwards compatibility, and because most XS code that reads floating point |
| 5983 | values can cope only with the decimal radix character being a dot. |
| 5984 | |
| 5985 | This macro makes sure the current C<LC_NUMERIC> state is set properly, to be |
| 5986 | aware of locale if the call to the XS or C code from the Perl program is |
| 5987 | from within the scope of a S<C<use locale>>; or to ignore locale if the call is |
| 5988 | instead from outside such scope. |
| 5989 | |
| 5990 | This macro is the start of wrapping the C or XS code; the wrap ending is done |
| 5991 | by calling the L</RESTORE_LC_NUMERIC> macro after the operation. Otherwise |
| 5992 | the state can be changed that will adversely affect other XS code. |
| 5993 | |
| 5994 | A call to L</DECLARATION_FOR_LC_NUMERIC_MANIPULATION> must have been made to |
| 5995 | declare at compile time a private variable used by this macro. This macro |
| 5996 | should be called as a single statement, not an expression, but with an empty |
| 5997 | argument list, like this: |
| 5998 | |
| 5999 | { |
| 6000 | DECLARATION_FOR_LC_NUMERIC_MANIPULATION; |
| 6001 | ... |
| 6002 | STORE_LC_NUMERIC_SET_TO_NEEDED(); |

| 6006 | } |
| 6007 | |
| 6008 | =for apidoc Am|void|RESTORE_LC_NUMERIC |
| 6009 | |
| 6010 | This is used in conjunction with one of the macros |
| 6011 | L</STORE_LC_NUMERIC_SET_TO_NEEDED> |
| 6012 | and |
| 6013 | L</STORE_LC_NUMERIC_FORCE_TO_UNDERLYING> |
| 6014 | |
| 6015 | to properly restore the C<LC_NUMERIC> state. |
| 6016 | |
| 6017 | A call to L</DECLARATION_FOR_LC_NUMERIC_MANIPULATION> must have been made to |
| 6018 | declare at compile time a private variable used by this macro and the two |
| 6019 | C<STORE> ones. This macro should be called as a single statement, not an |
| 6020 | expression, but with an empty argument list, like this: |
| 6021 | |

| 6694 | * To back up a bit (harhar): |
| 6695 | * |
| 6696 | * For IEEE 754 64-bit formats [1]: |
| 6697 | * |
| 6698 | * s 000 (mantissa all-zero) zero |
| 6699 | * s 000 (mantissa non-zero) subnormals (denormals) |
| 6700 | * s 001 ... 7fe normals |
| 6701 | * s 7ff q nan |
| 6702 | * |
| 6703 | * For IEEE 754 128-bit formats: |
| 6704 | * |
| 6705 | * s 0000 (mantissa all-zero) zero |
| 6706 | * s 0000 (mantissa non-zero) subnormals (denormals) |

| 6708 | * s 7fff q nan |
| 6709 | * |
| 6710 | * [1] this looks like big-endian, but applies equally to little-endian. |
| 6711 | * |
| 6712 | * s = Sign bit. Yes, zeros and nans can have negative sign, |
| 6713 | * the interpretation is application-specific. |
| 6714 | * |
| 6715 | * q = Quietness bit, the interpretation is platform-specific. |
| 6716 | * Most platforms have the most significant bit being one |
| 6717 | * meaning quiet, but some (older mips, hppa) have the msb |
| 6718 | * being one meaning signaling. Note that the above means |
| 6719 | * that on most platforms there cannot be signaling nan with |
| 6720 | * zero payload because that is identical with infinity; |
| 6721 | * while conversely on older mips/hppa there cannot be a quiet nan |
| 6722 | * because that is identical with infinity. |
| 6723 | * |
| 6724 | * Moreover, whether there is any behavioral difference |
| 6725 | * between quiet and signaling NaNs, depends on the platform. |

| 6739 | * |
| 6740 | * This means that in this format there are 61 bits available |
| 6741 | * for the nan payload. |
| 6742 | * |
| 6743 | * Note that the 32-bit x86 ABI cannot do signaling nans: the x87 |
| 6744 | * simply cannot preserve the bit. You can either use the 80-bit |
| 6745 | * extended precision (long double, -Duselongdouble), or use x86-64. |
| 6746 | * |
| 6747 | * In all platforms, the payload bytes (and bits, some of them are |
| 6748 | * often in a partial byte) themselves can be either all zero (x86), |
| 6749 | * all one (sparc or mips), or a mixture: in IEEE 754 128-bit double |
| 6750 | * or in a double-double, the first half of the payload can follow the |
| 6751 | * native double, while in the second half the payload can be all |
| 6752 | * zeros. (Therefore the mask for payload bits is not necessarily |
| 6753 | * identical to bit complement of the NaN.) Another way of putting |
| 6754 | * this: the payload for the default NaN might not be zero. |
| 6755 | * |
| 6756 | * For the x86 80-bit long doubles, the trailing bytes (the 80 bits |
| 6757 | * being 'packaged' in either 12 or 16 bytes) can be whatever random |
| 6758 | * garbage. |
| 6759 | * |
| 6760 | * Furthermore, the semantics of the sign bit on NaNs are platform-specific. |
| 6761 | * On normal floats, the sign bit being on means negative. But this may, |
| 6762 | * or may not, be reverted on NaNs: in other words, the default NaN might |
| 6763 | * have the sign bit on, and therefore look like negative if you look |
| 6764 | * at it at the bit level. |
| 6765 | * |
| 6766 | * NaN payloads are not propagated even on copies, or in arithmetics. |
| 6767 | * They *might* be, according to some rules, on your particular |
| 6768 | * cpu/os/compiler/libraries, but no guarantees. |
| 6769 | * |
| 6770 | * To summarize, on most platforms, and for 64-bit doubles |
| 6771 | * (using big-endian ordering here): |
| 6772 | * |
| 6773 | * [7FF8000000000000..7FFFFFFFFFFFFFFF] quiet |
| 6774 | * [FFF8000000000000..FFFFFFFFFFFFFFFF] quiet |
| 6775 | * [7FF0000000000001..7FF7FFFFFFFFFFFF] signaling |
| 6776 | * [FFF0000000000001..FFF7FFFFFFFFFFFF] signaling |
| 6777 | * |
| 6778 | * The C99 nan() is supposed to generate *quiet* NaNs. |
| 6779 | * |
| 6780 | * Note the asymmetry: |
| 6781 | * The 7FF0000000000000 is positive infinity, |
| 6782 | * the FFF0000000000000 is negative infinity. |
