-/* The i386 floating point hardware (the 387 compatible FPU, not the modern
- SSE/SSE2 hardware) has a controllable rounding precision. It is specified
- through the 'PC' bits in the FPU control word ('fctrl' register). (See
- the GNU libc i386 <fpu_control.h> header for details.)
-
- On some platforms, such as Linux or Solaris, the default precision setting
- is set to "extended precision". This means that 'long double' instructions
- operate correctly, but 'double' computations often produce slightly
- different results as on strictly IEEE 754 conforming systems.
-
- On some platforms, such as NetBSD, the default precision is set to
- "double precision". This means that 'long double' instructions will operate
- only as 'double', i.e. lead to wrong results. Similarly on FreeBSD 6.4, at
- least for the division of 'long double' numbers.
-
- The FPU control word is under control of the application, i.e. it is
- not required to be set either way by the ABI. (In fact, the i386 ABI
- https://www.linux-mips.org/pub/linux/mips/doc/ABI/abi386-4.pdf page 3-12 =
page 38
- is not clear about it. But in any case, gcc treats the control word
- like a "preserved" register: it emits code that assumes that the control
- word is preserved across calls, and it restores the control word at the
- end of functions that modify it.)
-
- See Vincent Lefèvre's page https://www.vinc17.net/research/extended.en.html
- for a good explanation.
- See
https://web.archive.org/web/20060905133417/http://www.uwsg.iu.edu/hypermail/linux/kernel/0103.0/0453.html

- If m<n, then q:=0 and r:=a.

- j:=j-1, r:=r*beta+a[j], q[j]:=floor(r/b[0]), r:=r-b[0]*q[j].
- Normalise [q[m-1],...,q[0]], yields q.
- If m>=n>1, perform a multiple-precision division:
- We have a/b < beta^(m-n+1).
- s:=intDsize-1-(highest bit in b[n-1]), 0<=s<intDsize.
- Shift a and b left by s bits, copying them. r:=a.

- For j=m-n,...,0: {Here 0 <= r < b*beta^(j+1).}
- Compute q* :
- q* := floor((r[j+n]*beta+r[j+n-1])/b[n-1]).
- In case of overflow (q* >= beta) set q* := beta-1.
- Compute c2 := ((r[j+n]*beta+r[j+n-1]) - q* * b[n-1])*beta + r[j+n-2]
- and c3 := b[n-2] * q*.
- {We have 0 <= c2 < 2*beta^2, even 0 <= c2 < beta^2 if no overflow
- occurred. Furthermore 0 <= c3 < beta^2.
- If there was overflow and
- r[j+n]*beta+r[j+n-1] - q* * b[n-1] >= beta, i.e. c2 >= beta^2,

- While c3 > c2, {Here 0 <= c2 < c3 < beta^2}
- Put q* := q* - 1, c2 := c2 + b[n-1]*beta, c3 := c3 - b[n-2].
- If q* > 0:
- Put r := r - b * q* * beta^j. In detail:
- [r[n+j],...,r[j]] := [r[n+j],...,r[j]] - q* * [b[n-1],...,b[0]].
- hence: u:=0, for i:=0 to n-1 do
- u := u + q* * b[i],
- r[j+i]:=r[j+i]-(u mod beta) (+ beta, if carry),
- u:=u div beta (+ 1, if carry in subtraction)
- r[n+j]:=r[n+j]-u.
- {Since always u = (q* * [b[i-1],...,b[0]] div beta^i) + 1
- < q* + 1 <= beta,
- the carry u does not overflow.}
- If a negative carry occurs, put q* := q* - 1
- and [r[n+j],...,r[j]] := [r[n+j],...,r[j]] +
[0,b[n-1],...,b[0]].
- Set q[j] := q*.
- Normalise [q[m-n],..,q[0]]; this yields the quotient q.
- Shift [r[n-1],...,r[0]] right by s bits and normalise; this yields the
- rest r.
- The room for q[j] can be allocated at the memory location of r[n+j].
- Finally, round-to-even:
- Shift r left by 1 bit.
- If r > b or if r = b and q[0] is odd, q := q+1.

- - On macOS 10.13 or newer, the use of %n in format

- format strings produces a fatal error (see
-
<https://android.googlesource.com/platform/bionic/+/41398d03b7e8e0dfb951660ae713e682e9fc0336>).

- On native Windows, if !WIDE_CHAR_VERSION, it's not a big
