5650 * Hence no surrogates nor non-characters, nor non-Unicode. Thus, if the input
5651 * passes this dfa, it will be for a well-formed, non-problematic code point
5652 * that can be returned immediately.
5654 * The "Implementation details" portion of
5655 * http://bjoern.hoehrmann.de/utf-8/decoder/dfa/ shows how
5656 * the first portion of the table maps each possible byte into a character
5657 * class. And that the classes for those bytes which are start bytes have been
5658 * carefully chosen so they serve as well to be used as a shift value to mask
5659 * off the leading 1 bits of the start byte. Unfortunately the addition of
5660 * being able to distinguish non-characters makes this not fully work. This is
5661 * because, now, the start bytes E1-EF have to be broken into 3 classes instead
5663 * 1) ED because it could be a surrogate
5664 * 2) EF because it could be a non-character
5665 * 3) the rest, which can never evaluate to a problematic code point.
5667 * Each of E1-EF has three leading 1 bits, then a 0. That means we could use a
5668 * shift (and hence class number) of either 3 or 4 to get a mask that works.
5669 * But that only allows two categories, and we need three. khw made the
5670 * decision to therefore treat the ED start byte as an error, so that the dfa
5671 * drops out immediately for that. In the dfa, classes 3 and 4 are used to
5672 * distinguish EF vs the rest. Then special code is used to deal with ED,
5673 * that's executed only when the dfa drops out. The code points started by ED
5674 * are half surrogates, and half hangul syllables. This means that 2048 of the
5675 * the hangul syllables (about 18%) take longer than all other non-problematic
5676 * code points to handle.
5678 * The changes to handle non-characters requires the addition of states and
5679 * classes to the dfa. (See the section on "Mapping bytes to character
5680 * classes" in the linked-to document for further explanation of the original

6305 This macro should be used as a statement. It declares a private variable
6306 (whose name begins with an underscore) that is needed by the other macros in
6307 this section. Failing to include this correctly should lead to a syntax error.
6308 For compatibility with C89 C compilers it should be placed in a block before
6309 any executable statements.
6311 =for apidoc Am|void|STORE_LC_NUMERIC_FORCE_TO_UNDERLYING
6313 This is used by XS code that that is C<LC_NUMERIC> locale-aware to force the
6314 locale for category C<LC_NUMERIC> to be what perl thinks is the current
6315 underlying locale. (The perl interpreter could be wrong about what the
6316 underlying locale actually is if some C or XS code has called the C library
6317 function L<setlocale(3)> behind its back; calling L</sync_locale> before calling
6318 this macro will update perl's records.)
6320 A call to L</DECLARATION_FOR_LC_NUMERIC_MANIPULATION> must have been made to
6321 declare at compile time a private variable used by this macro. This macro
6322 should be called as a single statement, not an expression, but with an empty
6323 argument list, like this:
6326 DECLARATION_FOR_LC_NUMERIC_MANIPULATION;
6328 STORE_LC_NUMERIC_FORCE_TO_UNDERLYING();
6330 RESTORE_LC_NUMERIC();
6334 The private variable is used to save the current locale state, so
6335 that the requisite matching call to L</RESTORE_LC_NUMERIC> can restore it.
6337 On threaded perls not operating with thread-safe functionality, this macro uses
6338 a mutex to force a critical section. Therefore the matching RESTORE should be
6339 close by, and guaranteed to be called.
6341 =for apidoc Am|void|STORE_LC_NUMERIC_SET_TO_NEEDED
6343 This is used to help wrap XS or C code that is C<LC_NUMERIC> locale-aware.
6344 This locale category is generally kept set to a locale where the decimal radix
6345 character is a dot, and the separator between groups of digits is empty. This
6346 is because most XS code that reads floating point numbers is expecting them to
6349 This macro makes sure the current C<LC_NUMERIC> state is set properly, to be
6350 aware of locale if the call to the XS or C code from the Perl program is
6351 from within the scope of a S<C<use locale>>; or to ignore locale if the call is
6352 instead from outside such scope.
6354 This macro is the start of wrapping the C or XS code; the wrap ending is done
6355 by calling the L</RESTORE_LC_NUMERIC> macro after the operation. Otherwise
6356 the state can be changed that will adversely affect other XS code.
6358 A call to L</DECLARATION_FOR_LC_NUMERIC_MANIPULATION> must have been made to
6359 declare at compile time a private variable used by this macro. This macro
6360 should be called as a single statement, not an expression, but with an empty

6378 This is used in conjunction with one of the macros
6379 L</STORE_LC_NUMERIC_SET_TO_NEEDED>

7300 * To back up a bit (harhar):
7302 * For IEEE 754 64-bit formats [1]:
7304 * s 000 (mantissa all-zero) zero
7305 * s 000 (mantissa non-zero) subnormals (denormals)
7306 * s 001 ... 7fe normals
7309 * For IEEE 754 128-bit formats:
7311 * s 0000 (mantissa all-zero) zero
7312 * s 0000 (mantissa non-zero) subnormals (denormals)
7313 * s 0001 ... 7ffe normals
7316 * [1] this looks like big-endian, but applies equally to little-endian.
7318 * s = Sign bit. Yes, zeros and nans can have negative sign,
7319 * the interpretation is application-specific.
7321 * q = Quietness bit, the interpretation is platform-specific.
7322 * Most platforms have the most significant bit being one
7323 * meaning quiet, but some (older mips, hppa) have the msb
7324 * being one meaning signaling. Note that the above means
7325 * that on most platforms there cannot be signaling nan with
7326 * zero payload because that is identical with infinity;
7327 * while conversely on older mips/hppa there cannot be a quiet nan
7328 * because that is identical with infinity.
7330 * Moreover, whether there is any behavioral difference
7331 * between quiet and signaling NaNs, depends on the platform.
7333 * x86 80-bit extended precision is different, the mantissa bits:
7335 * 63 62 61 30387+ pre-387 visual c
7336 * -------- ---- -------- --------
7337 * 0 0 0 invalid infinity
7338 * 0 0 1 invalid snan
7339 * 0 1 0 invalid snan
7340 * 0 1 1 invalid snan
7341 * 1 0 0 infinity snan 1.#INF
7342 * 1 0 1 snan 1.#SNAN
7343 * 1 1 0 qnan -1.#IND (x86 chooses this to negative)
7344 * 1 1 1 qnan 1.#QNAN
7346 * This means that in this format there are 61 bits available
7347 * for the nan payload.
7349 * Note that the 32-bit x86 ABI cannot do signaling nans: the x87
7350 * simply cannot preserve the bit. You can either use the 80-bit
7351 * extended precision (long double, -Duselongdouble), or use x86-64.
7353 * In all platforms, the payload bytes (and bits, some of them are
7354 * often in a partial byte) themselves can be either all zero (x86),
7355 * all one (sparc or mips), or a mixture: in IEEE 754 128-bit double
7356 * or in a double-double, the first half of the payload can follow the
7357 * native double, while in the second half the payload can be all
7358 * zeros. (Therefore the mask for payload bits is not necessarily
7359 * identical to bit complement of the NaN.) Another way of putting
7360 * this: the payload for the default NaN might not be zero.
7362 * For the x86 80-bit long doubles, the trailing bytes (the 80 bits
7363 * being 'packaged' in either 12 or 16 bytes) can be whatever random
7366 * Furthermore, the semantics of the sign bit on NaNs are platform-specific.
7367 * On normal floats, the sign bit being on means negative. But this may,
7368 * or may not, be reverted on NaNs: in other words, the default NaN might
7369 * have the sign bit on, and therefore look like negative if you look
7370 * at it at the bit level.
7372 * NaN payloads are not propagated even on copies, or in arithmetics.
7373 * They *might* be, according to some rules, on your particular
7374 * cpu/os/compiler/libraries, but no guarantees.
7376 * To summarize, on most platforms, and for 64-bit doubles
7377 * (using big-endian ordering here):
7379 * [7FF8000000000000..7FFFFFFFFFFFFFFF] quiet
7380 * [FFF8000000000000..FFFFFFFFFFFFFFFF] quiet
7381 * [7FF0000000000001..7FF7FFFFFFFFFFFF] signaling
7382 * [FFF0000000000001..FFF7FFFFFFFFFFFF] signaling
7384 * The C99 nan() is supposed to generate *quiet* NaNs.
7386 * Note the asymmetry:
7387 * The 7FF0000000000000 is positive infinity,
7388 * the FFF0000000000000 is negative infinity.
7391 /* NVMANTBITS is the number of _real_ mantissa bits in an NV.
7392 * For the standard IEEE 754 fp this number is usually one less that
7393 * *DBL_MANT_DIG because of the implicit (aka hidden) bit, which isn't
7394 * real. For the 80-bit extended precision formats (x86*), the number
7395 * of mantissa bits... depends. For normal floats, it's 64. But for
7396 * the inf/nan, it's different (zero for inf, 61 for nan).
7397 * NVMANTBITS works for normal floats. */
