    Assuming the script is a Bourne shell script, the first line of the

    and for ksh, the first line should be

    The script should then set the variable IFS to the string
    consisting of <space>, <tab>, and <newline>.  After this (*not*
    before!), the PATH variable should be set to a reasonable value and
    exported.  Do not expect the PATH to have a reasonable value, so do
    not trust the old value of PATH.  You should then set the umask of
    the program by calling

    If you plan to change directories, you should either unset CDPATH
    or set it to a good value.  Setting CDPATH to just ``.'' (dot) is a
    good idea.
    If, for some reason, you want to use csh, the first line should be
-	#!/bin/csh -fb

    You should then set the path variable to something reasonable,

-**	include unnecessary global variables, burying important tables
-**	in unrelated sourcefiles, putting functions in include files,
-**	using seemingly-descriptive variable names for different purposes,
-**	calls to empty subroutines and a host of others.

-	 *   4*ndigits <= DBL_MIN_EXP - DBL_MANT_DIG - LONG_MIN/2
-	 *   4*ndigits <= LONG_MAX/2 + 1 - DBL_MAX_EXP
-	 *
-	 * If either of these inequalities is not satisfied, a ValueError is

-	 *                    = DBL_MAX_EXP
-	 *

-	   of bits in v, so that 2**(n-1) <= v < 2**n, and n > DBL_MANT_DIG.
-
-	   Some terminology: the *rounding bit* of v is the 1st bit of v that
-	   will be rounded away (bit n - DBL_MANT_DIG - 1); the *parity bit*
-	   is the bit immediately above.  The round-half-to-even rule says
-	   that we round up if the rounding bit is set, unless v is exactly
-	   halfway between two floats and the parity bit is zero.
-
-	   Write d[0] ... d[m] for the digits of v, least to most significant.
-	   Let rnd_bit be the index of the rounding bit, and rnd_digit the
-	   index of the PyLong digit containing the rounding bit.  Then the
-	   bits of the digit d[rnd_digit] look something like:
-
-	              rounding bit
-	                  |
-	                  v
-	      msb -> sssssrttttttttt <- lsb
-	                 ^
-	                 |
-	              parity bit
-
-	   where 's' represents a 'significant bit' that will be included in
-	   the mantissa of the result, 'r' is the rounding bit, and 't'
-	   represents a 'trailing bit' following the rounding bit.  Note that
-	   if the rounding bit is at the top of d[rnd_digit] then the parity
-	   bit will be the lsb of d[rnd_digit+1].  If we set
-
-	      lsb = 1 << (rnd_bit % PyLong_SHIFT)
-
-	   then d[rnd_digit] & (PyLong_BASE - 2*lsb) selects just the
-	   significant bits of d[rnd_digit], d[rnd_digit] & (lsb-1) gets the
-	   trailing bits, and d[rnd_digit] & lsb gives the rounding bit.
-
-	   We initialize the double x to the integer given by digits
-	   d[rnd_digit:m-1], but with the rounding bit and trailing bits of
-	   d[rnd_digit] masked out.  So the value of x comes from the top
-	   DBL_MANT_DIG bits of v, multiplied by 2*lsb.  Note that in the loop
-	   that produces x, all floating-point operations are exact (assuming
-	   that FLT_RADIX==2).  Now if we're rounding down, the value we want
-	   to return is simply
-
-	      x * 2**(PyLong_SHIFT * rnd_digit).
-
-	   and if we're rounding up, it's
-
-	      (x + 2*lsb) * 2**(PyLong_SHIFT * rnd_digit).
-
-	   Under the round-half-to-even rule, we round up if, and only
-	   if, the rounding bit is set *and* at least one of the
-	   following three conditions is satisfied:
-
-	      (1) the parity bit is set, or
-	      (2) at least one of the trailing bits of d[rnd_digit] is set, or
-	      (3) at least one of the digits d[i], 0 <= i < rnd_digit
-	         is nonzero.
-
-	   Finally, we have to worry about overflow.  If v >= 2**DBL_MAX_EXP,
-	   or equivalently n > DBL_MAX_EXP, then overflow occurs.  If v <
-	   2**DBL_MAX_EXP then we're usually safe, but there's a corner case
-	   to consider: if v is very close to 2**DBL_MAX_EXP then it's
-	   possible that v is rounded up to exactly 2**DBL_MAX_EXP, and then

    There are two possible race conditions:

    (2) AddPendingCall() calls made while pending calls are being processed.

    (1) is very unlikely because typically signal delivery

+         1 for a possible decimal point
+         2 for a possible [eE][+-]
+         1 for each digit of the exponent;  if we allow 19 digits
+           total then we're safe up to exponents of 2**63.
+         1 for the trailing nul byte
+
+       This gives a total of 24 + the number of digits in the significand,
+       and the number of digits in the significand is:
+
+         for 'g' format: at most precision, except possibly
+           when precision == 0, when it's 1.
+         for 'e' format: precision+1
+         for 'f' format: precision digits after the point, at least 1
+           before.  To figure out how many digits appear before the point
+           we have to examine the size of the number.  If fabs(val) < 1.0
+           then there will be only one digit before the point.  If
+           fabs(val) >= 1.0, then there are at most
+
+         1+floor(log10(ceiling(fabs(val))))
+
+           digits before the point (where the 'ceiling' allows for the
+           possibility that the rounding rounds the integer part of val
+           up).  A safe upper bound for the above quantity is
+           1+floor(exp/3), where exp is the unique integer such that 0.5
+           <= fabs(val)/2**exp < 1.0.  This exp can be obtained from
+           frexp.
+
+       So we allow room for precision+1 digits for all formats, plus an
+       extra floor(exp/3) digits for 'f' format.
