5621 * Hence no surrogates nor non-characters, nor non-Unicode. Thus, if the input
5622 * passes this dfa, it will be for a well-formed, non-problematic code point
5623 * that can be returned immediately.
5625 * The "Implementation details" portion of
5626 * http://bjoern.hoehrmann.de/utf-8/decoder/dfa/ shows how
5627 * the first portion of the table maps each possible byte into a character
5628 * class. And that the classes for those bytes which are start bytes have been
5629 * carefully chosen so they serve as well to be used as a shift value to mask
5630 * off the leading 1 bits of the start byte. Unfortunately the addition of
5631 * being able to distinguish non-characters makes this not fully work. This is
5632 * because, now, the start bytes E1-EF have to be broken into 3 classes instead
5634 * 1) ED because it could be a surrogate
5635 * 2) EF because it could be a non-character
5636 * 3) the rest, which can never evaluate to a problematic code point.
5638 * Each of E1-EF has three leading 1 bits, then a 0. That means we could use a
5639 * shift (and hence class number) of either 3 or 4 to get a mask that works.
5640 * But that only allows two categories, and we need three. khw made the
5641 * decision to therefore treat the ED start byte as an error, so that the dfa
5642 * drops out immediately for that. In the dfa, classes 3 and 4 are used to
5643 * distinguish EF vs the rest. Then special code is used to deal with ED,
5644 * that's executed only when the dfa drops out. The code points started by ED
5645 * are half surrogates, and half hangul syllables. This means that 2048 of the
5646 * the hangul syllables (about 18%) take longer than all other non-problematic
5647 * code points to handle.
5649 * The changes to handle non-characters requires the addition of states and
5650 * classes to the dfa. (See the section on "Mapping bytes to character
5651 * classes" in the linked-to document for further explanation of the original

6268 This macro should be used as a statement. It declares a private variable
6269 (whose name begins with an underscore) that is needed by the other macros in
6270 this section. Failing to include this correctly should lead to a syntax error.
6271 For compatibility with C89 C compilers it should be placed in a block before
6272 any executable statements.
6274 =for apidoc Am|void|STORE_LC_NUMERIC_FORCE_TO_UNDERLYING
6276 This is used by XS code that that is C<LC_NUMERIC> locale-aware to force the
6277 locale for category C<LC_NUMERIC> to be what perl thinks is the current
6278 underlying locale. (The perl interpreter could be wrong about what the
6279 underlying locale actually is if some C or XS code has called the C library
6280 function L<setlocale(3)> behind its back; calling L</sync_locale> before calling
6281 this macro will update perl's records.)
6283 A call to L</DECLARATION_FOR_LC_NUMERIC_MANIPULATION> must have been made to
6284 declare at compile time a private variable used by this macro. This macro
6285 should be called as a single statement, not an expression, but with an empty
6286 argument list, like this:
6289 DECLARATION_FOR_LC_NUMERIC_MANIPULATION;
6291 STORE_LC_NUMERIC_FORCE_TO_UNDERLYING();
6293 RESTORE_LC_NUMERIC();
6297 The private variable is used to save the current locale state, so
6298 that the requisite matching call to L</RESTORE_LC_NUMERIC> can restore it.
6300 On threaded perls not operating with thread-safe functionality, this macro uses
6301 a mutex to force a critical section. Therefore the matching RESTORE should be
6302 close by, and guaranteed to be called.
6304 =for apidoc Am|void|STORE_LC_NUMERIC_SET_TO_NEEDED
6306 This is used to help wrap XS or C code that is C<LC_NUMERIC> locale-aware.
6307 This locale category is generally kept set to a locale where the decimal radix
6308 character is a dot, and the separator between groups of digits is empty. This
6309 is because most XS code that reads floating point numbers is expecting them to
6312 This macro makes sure the current C<LC_NUMERIC> state is set properly, to be
6313 aware of locale if the call to the XS or C code from the Perl program is
6314 from within the scope of a S<C<use locale>>; or to ignore locale if the call is
6315 instead from outside such scope.
6317 This macro is the start of wrapping the C or XS code; the wrap ending is done
6318 by calling the L</RESTORE_LC_NUMERIC> macro after the operation. Otherwise
6319 the state can be changed that will adversely affect other XS code.
6321 A call to L</DECLARATION_FOR_LC_NUMERIC_MANIPULATION> must have been made to
6322 declare at compile time a private variable used by this macro. This macro
6323 should be called as a single statement, not an expression, but with an empty
6324 argument list, like this:

6337 close by, and guaranteed to be called.

6341 This is used in conjunction with one of the macros
6342 L</STORE_LC_NUMERIC_SET_TO_NEEDED>
6343 and L</STORE_LC_NUMERIC_FORCE_TO_UNDERLYING> to properly restore the
6344 C<LC_NUMERIC> state.

7277 * To back up a bit (harhar):
7279 * For IEEE 754 64-bit formats [1]:
7281 * s 000 (mantissa all-zero) zero
7282 * s 000 (mantissa non-zero) subnormals (denormals)
7283 * s 001 ... 7fe normals
7286 * For IEEE 754 128-bit formats:
7288 * s 0000 (mantissa all-zero) zero
7289 * s 0000 (mantissa non-zero) subnormals (denormals)
7290 * s 0001 ... 7ffe normals
7293 * [1] this looks like big-endian, but applies equally to little-endian.
7295 * s = Sign bit. Yes, zeros and nans can have negative sign,
7296 * the interpretation is application-specific.
7298 * q = Quietness bit, the interpretation is platform-specific.
7299 * Most platforms have the most significant bit being one
7300 * meaning quiet, but some (older mips, hppa) have the msb
7301 * being one meaning signaling. Note that the above means
7302 * that on most platforms there cannot be signaling nan with
7303 * zero payload because that is identical with infinity;
7304 * while conversely on older mips/hppa there cannot be a quiet nan
7305 * because that is identical with infinity.
7307 * Moreover, whether there is any behavioral difference
7308 * between quiet and signaling NaNs, depends on the platform.
7310 * x86 80-bit extended precision is different, the mantissa bits:
7312 * 63 62 61 30387+ pre-387 visual c
7313 * -------- ---- -------- --------
7314 * 0 0 0 invalid infinity
7315 * 0 0 1 invalid snan
7316 * 0 1 0 invalid snan
7317 * 0 1 1 invalid snan
7318 * 1 0 0 infinity snan 1.#INF
7319 * 1 0 1 snan 1.#SNAN
7320 * 1 1 0 qnan -1.#IND (x86 chooses this to negative)
7321 * 1 1 1 qnan 1.#QNAN
7323 * This means that in this format there are 61 bits available
7324 * for the nan payload.
7326 * Note that the 32-bit x86 ABI cannot do signaling nans: the x87
7327 * simply cannot preserve the bit. You can either use the 80-bit
7328 * extended precision (long double, -Duselongdouble), or use x86-64.
7330 * In all platforms, the payload bytes (and bits, some of them are
7331 * often in a partial byte) themselves can be either all zero (x86),
7332 * all one (sparc or mips), or a mixture: in IEEE 754 128-bit double
7333 * or in a double-double, the first half of the payload can follow the
7334 * native double, while in the second half the payload can be all
7335 * zeros. (Therefore the mask for payload bits is not necessarily
7336 * identical to bit complement of the NaN.) Another way of putting
7337 * this: the payload for the default NaN might not be zero.
7339 * For the x86 80-bit long doubles, the trailing bytes (the 80 bits
7340 * being 'packaged' in either 12 or 16 bytes) can be whatever random
7343 * Furthermore, the semantics of the sign bit on NaNs are platform-specific.
7344 * On normal floats, the sign bit being on means negative. But this may,
7345 * or may not, be reverted on NaNs: in other words, the default NaN might
7346 * have the sign bit on, and therefore look like negative if you look
7347 * at it at the bit level.
7349 * NaN payloads are not propagated even on copies, or in arithmetics.
7350 * They *might* be, according to some rules, on your particular
7351 * cpu/os/compiler/libraries, but no guarantees.
7353 * To summarize, on most platforms, and for 64-bit doubles
7354 * (using big-endian ordering here):
7356 * [7FF8000000000000..7FFFFFFFFFFFFFFF] quiet
7357 * [FFF8000000000000..FFFFFFFFFFFFFFFF] quiet
7358 * [7FF0000000000001..7FF7FFFFFFFFFFFF] signaling
7359 * [FFF0000000000001..FFF7FFFFFFFFFFFF] signaling
7361 * The C99 nan() is supposed to generate *quiet* NaNs.
7363 * Note the asymmetry:
7364 * The 7FF0000000000000 is positive infinity,
7365 * the FFF0000000000000 is negative infinity.
7368 /* NVMANTBITS is the number of _real_ mantissa bits in an NV.
7369 * For the standard IEEE 754 fp this number is usually one less that
7370 * *DBL_MANT_DIG because of the implicit (aka hidden) bit, which isn't
7371 * real. For the 80-bit extended precision formats (x86*), the number
7372 * of mantissa bits... depends. For normal floats, it's 64. But for
7373 * the inf/nan, it's different (zero for inf, 61 for nan).
7374 * NVMANTBITS works for normal floats. */
