+ Rename intdiv it intdiv0 and require enabling at configure time.
+
+ * awkgram.y (tokentab): Bracket intdiv0 in #ifdef SUPPLY_INTDIV.
+ (snode): Similar.
+ * builtin.c (do_intdiv): Bracket in #ifdef SUPPLY_INTDIV.
+ * mpfr.c (do_mpfr_intdiv): Bracket in #ifdef SUPPLY_INTDIV.
+ * configure.ac: Add --enable-builtin-intdiv0 option. If enabled,
+ also revise doc/gawktexi.in.

* builtin.c (do_intdiv): Use DEREF on the arguments.
Thanks to Andrew Schorr for finding the problem.
* mpfr.c (do_mpfr_intdiv): Return -1 if numerator or denominator

-'intdiv(NUMERATOR, DENOMINATOR, RESULT)'
- Perform integer division, similar to the standard C 'div()'
- function. First, truncate 'numerator' and 'denominator' towards
- zero, creating integer values. Clear the 'result' array, and then
- set 'result["quotient"]' to the result of 'numerator /
- denominator', truncated towards zero to an integer, and set
- 'result["remainder"]' to the result of 'numerator % denominator',
- truncated towards zero to an integer. Attempting division by zero
- causes a fatal error. The function returns zero upon success, and
- -1 upon error.
-
- This function is primarily intended for use with arbitrary length
- integers; it avoids creating MPFR arbitrary precision

When dividing two arbitrary precision integers with either '/' or
'%', the result is typically an arbitrary precision floating point value
-(unless the denominator evenly divides into the numerator). In order to
-do integer division or remainder with arbitrary precision integers, use
-the built-in 'intdiv()' function (*note Numeric Functions::).
-
- You can simulate the 'intdiv()' function in standard 'awk' using this
-user-defined function:
-
- # intdiv --- do integer division
-
- function intdiv(numerator, denominator, result)
- {
- split("", result)
-
- numerator = int(numerator)
- denominator = int(denominator)
- result["quotient"] = int(numerator / denominator)
- result["remainder"] = int(numerator % denominator)
-
- return 0.0
- }
-
- The following example program, contributed by Katie Wasserman, uses
-'intdiv()' to compute the digits of pi to as many places as you choose
-to set:
-
- # pi.awk --- compute the digits of pi
-
- BEGIN {
- digits = 100000
- two = 2 * 10 ^ digits
- pi = two
- for (m = digits * 4; m > 0; --m) {
- d = m * 2 + 1
- x = pi * m
- intdiv(x, d, result)
- pi = result["quotient"]
- pi = pi + two
- }
- print pi
- }
-
- When asked about the algorithm used, Katie replied:
-
- It's not that well known but it's not that obscure either. It's
- Euler's modification to Newton's method for calculating pi. Take a
- look at lines (23) - (25) here:
- <http://mathworld.wolfram.com/PiFormulas.html>.
-
- The algorithm I wrote simply expands the multiply by 2 and works
- from the innermost expression outwards. I used this to program HP
- calculators because it's quite easy to modify for tiny memory
- devices with smallish word sizes. See
