5648 * Hence no surrogates nor non-characters, nor non-Unicode. Thus, if the input
5649 * passes this dfa, it will be for a well-formed, non-problematic code point
5650 * that can be returned immediately.
5652 * The "Implementation details" portion of
5653 * http://bjoern.hoehrmann.de/utf-8/decoder/dfa/ shows how
5654 * the first portion of the table maps each possible byte into a character
5655 * class. And that the classes for those bytes which are start bytes have been
5656 * carefully chosen so they serve as well to be used as a shift value to mask
5657 * off the leading 1 bits of the start byte. Unfortunately the addition of
5658 * being able to distinguish non-characters makes this not fully work. This is
5659 * because, now, the start bytes E1-EF have to be broken into 3 classes instead
5661 * 1) ED because it could be a surrogate
5662 * 2) EF because it could be a non-character
5663 * 3) the rest, which can never evaluate to a problematic code point.
5665 * Each of E1-EF has three leading 1 bits, then a 0. That means we could use a
5666 * shift (and hence class number) of either 3 or 4 to get a mask that works.
5667 * But that only allows two categories, and we need three. khw made the
5668 * decision to therefore treat the ED start byte as an error, so that the dfa
5669 * drops out immediately for that. In the dfa, classes 3 and 4 are used to
5670 * distinguish EF vs the rest. Then special code is used to deal with ED,
5671 * that's executed only when the dfa drops out. The code points started by ED
5672 * are half surrogates, and half hangul syllables. This means that 2048 of the
5673 * the hangul syllables (about 18%) take longer than all other non-problematic
5674 * code points to handle.
5676 * The changes to handle non-characters requires the addition of states and
5677 * classes to the dfa. (See the section on "Mapping bytes to character
5678 * classes" in the linked-to document for further explanation of the original

6303 This macro should be used as a statement. It declares a private variable
6304 (whose name begins with an underscore) that is needed by the other macros in
6305 this section. Failing to include this correctly should lead to a syntax error.
6306 For compatibility with C89 C compilers it should be placed in a block before
6307 any executable statements.
6309 =for apidoc Am|void|STORE_LC_NUMERIC_FORCE_TO_UNDERLYING
6311 This is used by XS code that that is C<LC_NUMERIC> locale-aware to force the
6312 locale for category C<LC_NUMERIC> to be what perl thinks is the current
6313 underlying locale. (The perl interpreter could be wrong about what the
6314 underlying locale actually is if some C or XS code has called the C library
6315 function L<setlocale(3)> behind its back; calling L</sync_locale> before calling
6316 this macro will update perl's records.)
6318 A call to L</DECLARATION_FOR_LC_NUMERIC_MANIPULATION> must have been made to
6319 declare at compile time a private variable used by this macro. This macro
6320 should be called as a single statement, not an expression, but with an empty
6321 argument list, like this:
6324 DECLARATION_FOR_LC_NUMERIC_MANIPULATION;
6326 STORE_LC_NUMERIC_FORCE_TO_UNDERLYING();
6328 RESTORE_LC_NUMERIC();
6332 The private variable is used to save the current locale state, so
6333 that the requisite matching call to L</RESTORE_LC_NUMERIC> can restore it.
6335 On threaded perls not operating with thread-safe functionality, this macro uses
6336 a mutex to force a critical section. Therefore the matching RESTORE should be
6337 close by, and guaranteed to be called.
6339 =for apidoc Am|void|STORE_LC_NUMERIC_SET_TO_NEEDED
6341 This is used to help wrap XS or C code that is C<LC_NUMERIC> locale-aware.
6342 This locale category is generally kept set to a locale where the decimal radix
6343 character is a dot, and the separator between groups of digits is empty. This
6344 is because most XS code that reads floating point numbers is expecting them to
6347 This macro makes sure the current C<LC_NUMERIC> state is set properly, to be
6348 aware of locale if the call to the XS or C code from the Perl program is
6349 from within the scope of a S<C<use locale>>; or to ignore locale if the call is
6350 instead from outside such scope.
6352 This macro is the start of wrapping the C or XS code; the wrap ending is done
6353 by calling the L</RESTORE_LC_NUMERIC> macro after the operation. Otherwise
6354 the state can be changed that will adversely affect other XS code.
6356 A call to L</DECLARATION_FOR_LC_NUMERIC_MANIPULATION> must have been made to
6357 declare at compile time a private variable used by this macro. This macro
6358 should be called as a single statement, not an expression, but with an empty
6359 argument list, like this:
6362 DECLARATION_FOR_LC_NUMERIC_MANIPULATION;
6364 STORE_LC_NUMERIC_SET_TO_NEEDED();
6366 RESTORE_LC_NUMERIC();
6370 On threaded perls not operating with thread-safe functionality, this macro uses
6371 a mutex to force a critical section. Therefore the matching RESTORE should be
6372 close by, and guaranteed to be called.

6376 This is used in conjunction with one of the macros
6377 L</STORE_LC_NUMERIC_SET_TO_NEEDED>
6378 and L</STORE_LC_NUMERIC_FORCE_TO_UNDERLYING> to properly restore the
6379 C<LC_NUMERIC> state.
6381 A call to L</DECLARATION_FOR_LC_NUMERIC_MANIPULATION> must have been made to
6382 declare at compile time a private variable used by this macro and the two

7312 * To back up a bit (harhar):
7314 * For IEEE 754 64-bit formats [1]:
7316 * s 000 (mantissa all-zero) zero
7317 * s 000 (mantissa non-zero) subnormals (denormals)
7318 * s 001 ... 7fe normals
7321 * For IEEE 754 128-bit formats:
7323 * s 0000 (mantissa all-zero) zero
7324 * s 0000 (mantissa non-zero) subnormals (denormals)
7325 * s 0001 ... 7ffe normals
7328 * [1] this looks like big-endian, but applies equally to little-endian.
7330 * s = Sign bit. Yes, zeros and nans can have negative sign,
7331 * the interpretation is application-specific.
7333 * q = Quietness bit, the interpretation is platform-specific.
7334 * Most platforms have the most significant bit being one
7335 * meaning quiet, but some (older mips, hppa) have the msb
7336 * being one meaning signaling. Note that the above means
7337 * that on most platforms there cannot be signaling nan with
7338 * zero payload because that is identical with infinity;
7339 * while conversely on older mips/hppa there cannot be a quiet nan
7340 * because that is identical with infinity.
7342 * Moreover, whether there is any behavioral difference
7343 * between quiet and signaling NaNs, depends on the platform.
7345 * x86 80-bit extended precision is different, the mantissa bits:
7347 * 63 62 61 30387+ pre-387 visual c
7348 * -------- ---- -------- --------
7349 * 0 0 0 invalid infinity
7350 * 0 0 1 invalid snan
7351 * 0 1 0 invalid snan
7352 * 0 1 1 invalid snan
7353 * 1 0 0 infinity snan 1.#INF
7354 * 1 0 1 snan 1.#SNAN
7355 * 1 1 0 qnan -1.#IND (x86 chooses this to negative)
7356 * 1 1 1 qnan 1.#QNAN
7358 * This means that in this format there are 61 bits available
7359 * for the nan payload.
7361 * Note that the 32-bit x86 ABI cannot do signaling nans: the x87
7362 * simply cannot preserve the bit. You can either use the 80-bit
7363 * extended precision (long double, -Duselongdouble), or use x86-64.
7365 * In all platforms, the payload bytes (and bits, some of them are
7366 * often in a partial byte) themselves can be either all zero (x86),
7367 * all one (sparc or mips), or a mixture: in IEEE 754 128-bit double
7368 * or in a double-double, the first half of the payload can follow the
7369 * native double, while in the second half the payload can be all
7370 * zeros. (Therefore the mask for payload bits is not necessarily
7371 * identical to bit complement of the NaN.) Another way of putting
7372 * this: the payload for the default NaN might not be zero.
7374 * For the x86 80-bit long doubles, the trailing bytes (the 80 bits
7375 * being 'packaged' in either 12 or 16 bytes) can be whatever random
7378 * Furthermore, the semantics of the sign bit on NaNs are platform-specific.
7379 * On normal floats, the sign bit being on means negative. But this may,
7380 * or may not, be reverted on NaNs: in other words, the default NaN might
7381 * have the sign bit on, and therefore look like negative if you look
7382 * at it at the bit level.
7384 * NaN payloads are not propagated even on copies, or in arithmetics.
7385 * They *might* be, according to some rules, on your particular
7386 * cpu/os/compiler/libraries, but no guarantees.
7388 * To summarize, on most platforms, and for 64-bit doubles
7389 * (using big-endian ordering here):
7391 * [7FF8000000000000..7FFFFFFFFFFFFFFF] quiet
7392 * [FFF8000000000000..FFFFFFFFFFFFFFFF] quiet
7393 * [7FF0000000000001..7FF7FFFFFFFFFFFF] signaling
7394 * [FFF0000000000001..FFF7FFFFFFFFFFFF] signaling
7396 * The C99 nan() is supposed to generate *quiet* NaNs.
7398 * Note the asymmetry:
7399 * The 7FF0000000000000 is positive infinity,
7400 * the FFF0000000000000 is negative infinity.
7403 /* NVMANTBITS is the number of _real_ mantissa bits in an NV.
7404 * For the standard IEEE 754 fp this number is usually one less that
7405 * *DBL_MANT_DIG because of the implicit (aka hidden) bit, which isn't
7406 * real. For the 80-bit extended precision formats (x86*), the number
7407 * of mantissa bits... depends. For normal floats, it's 64. But for
7408 * the inf/nan, it's different (zero for inf, 61 for nan).
7409 * NVMANTBITS works for normal floats. */
