Builtin functions

	There is a large number of built-in functions.	Many of the
	functions work on several types of arguments, whereas some only
	work for the correct types (e.g., numbers or strings).	In the
	following description, this is indicated by whether or not the
	description refers to values or numbers.  This display is generated
	by the 'show builtin' command.

	The config function sets or reads the value of a configuration
	parameter.  The first argument is a string which names the parameter
	to be set or read.  If only one argument is given, then the current
	value of the named parameter is returned.  If two arguments are given,
	then the named parameter is set to the value of the second argument,
	and the old value of the parameter is returned.	 Therefore you can
	change a parameter and restore its old value later.  The possible
	parameters are explained in the next section.

	The scale function multiplies or divides a number by a power of 2.
	This is used for fractional calculations, unlike the << and >>
	operators, which are only defined for integers.	 For example,
	scale(6, -3) is 3/4.

	The quomod function is used to obtain both the quotient and remainder
	of a division in one operation.	 The first two arguments a and b are
	the numbers to be divided.  The last two arguments c and d are two
	variables which will be assigned the quotient and remainder.  For
	nonnegative arguments, the results are equivalent to computing a//b
	and a%b.  If a is negative and the remainder is nonzero, then the
	quotient will be one less than a//b.  This makes the following three
	properties always hold:	 The quotient c is always an integer.  The
	remainder d is always 0 <= d < b.  The equation a = b * c + d always
	holds.	This function returns 0 if there is no remainder, and 1 if
	there is a remainder.  For examples, quomod(10, 3, x, y) sets x to 3,
	y to 1, and returns the value 1, and quomod(-4, 3.14159, x, y) sets x
	to -2, y to 2.28318, and returns the value 1.

	The eval function accepts a string argument and evaluates the
	expression represented by the string and returns its value.
	The expression can include function calls and variable references.
	For example, eval("fact(3) + 7") returns 13.  When combined with
	the prompt function, this allows the calculator to read values from
	the user.  For example, x=eval(prompt("Number: ")) sets x to the
	value input by the user.

	The digit and bit functions return individual digits of a number,
	either in base 10 or in base 2, where the lowest digit of a number
	is at digit position 0.	 For example, digit(5678, 3) is 5, and
	bit(0b1000100, 2) is 1.	 Negative digit positions indicate places
	to the right of the decimal or binary point, so that for example,
	digit(3.456, -1) is 4.

	The ptest builtin is a primality testing function.  The
	1st argument is the suspected prime to be tested.  The
	absolute value of the 2nd argument is an iteration count.

	If ptest is called with only 2 args, the 3rd argument is
	assumed to be 0.  If ptest is called with only 1 arg, the
	2nd argument is assumed to be 1.  Thus, the following
	calls are equivalent:

		ptest(a)
		ptest(a,1)
		ptest(a,1,0)

	Normally ptest performs a some checks to determine if the
	value is divisable by some trivial prime.  If the 2nd
	argument is < 0, then the trivial check is omitted.

	For example, ptest(a,10) performs the same work as:

		ptest(a,-3)	(7 tests without trivial check)
		ptest(a,-7,3)	(3 more tests without the trivial check)

	The ptest function returns 0 if the number is definitely not
	prime, and 1 is the number is probably prime.  The chance
	of a number which is probably prime being actually composite
	is less than 1/4 raised to the power of the iteration count.
	For example, for a random number p, ptest(p, 10) incorrectly
	returns 1 less than once in every million numbers, and you
	will probably never find a number where ptest(p, 20) gives
	the wrong answer.

	The first 3 args of nextcand and prevcand functions are the same
	arguments as ptest.  But unlike ptest, nextcand and prevcand return
	the next and previous values for which ptest is true.

	For example, nextcand(2^1000) returns 2^1000+297 because
	2^1000+297 is the smallest value x > 2^1000 for which
	ptest(x,1) is true.  And for example, prevcand(2^31-1,10,5)
	returns 2147483629 (2^31-19) because 2^31-19 is the largest
	value y < 2^31-1 for which ptest(y,10,5) is true.

	The nextcand and prevcand functions also have a 5 argument form:

		nextcand(num, count, skip, modval, modulus)
		prevcand(num, count, skip, modval, modulus)

	return the smallest (or largest) value ans > num (or < num) that
	is also == modval % modulus for which ptest(ans,count,skip) is true.

	The builtins nextprime(x) and prevprime(x) return the
	next and previous primes with respect to x respectively.
	As of this release, x must be < 2^32.  With one argument, they
	will return an error if x is out of range.  With two arguments,
	they will not generate an error but instead will return y.

	The builtin function pix(x) returns the number of primes <= x.
	As of this release, x must be < 2^32.  With one argument, pix(x)
	will return an error if x is out of range.  With two arguments,
	pix(x,y) will not generate an error but instead will return y.

	The builtin function factor may be used to search for the
	smallest factor of a given number.  The call factor(x,y)
	will attempt to find the smallest factor of x < min(x,y).
	As of this release, y must be < 2^32.  If y is omitted, y
	is assumed to be 2^32-1.

	If x < 0, factor(x,y) will return -1.  If no factor <
	min(x,y) is found, factor(x,y) will return 1.  In all other
	cases, factor(x,y) will return the smallest prime factor
	of x.  Note except for the case when abs(x) == 1, factor(x,y)
	will not return x.

	If factor is called with y that is too large, or if x or y
	is not an integer, calc will report an error.  If a 3rd argument
	is given, factor will return that value instead.  For example,
	factor(1/2,b,c) will return c instead of issuing an error.

	The builtin lfactor(x,y) searches a number of primes instead
	of below a limit.  As of this release, y must be <= 203280221
	(y <= pix(2^32-1)).  In all other cases, lfactor is operates
	in the same way as factor.

	If lfactor is called with y that is too large, or if x or y
	is not an integer, calc will report an error.  If a 3rd argument
	is given, lfactor will return that value instead.  For example,
	lfactor(1/2,b,c) will return c instead of issuing an error.

	The lfactor function is slower than factor.  If possible factor
	should be used instead of lfactor.

	The builtin isprime(x) will attempt to determine if x is prime.
	As of this release, x must be < 2^32.  With one argument, isprime(x)
	will return an error if x is out of range.  With two arguments,
	isprime(x,y) will not generate an error but instead will return y.

	The functions rcin, rcmul, rcout, rcpow, and rcsq are used to
	perform modular arithmetic calculations for large odd numbers
	faster than the usual methods.	To do this, you first use the
	rcin function to convert all input values into numbers which are
	in a format called REDC format.	 Then you use rcmul, rcsq, and
	rcpow to multiply such numbers together to produce results also
	in REDC format.	 Finally, you use rcout to convert a number in
	REDC format back to a normal number.  The addition, subtraction,
	negation, and equality comparison between REDC numbers are done
	using the normal modular methods.  For example, to calculate the
	value 13 * 17 + 1 (mod 11), you could use:

		p = 11;
		t1 = rcin(13, p);
		t2 = rcin(17, p);
		t3 = rcin(1, p);
		t4 = rcmul(t1, t2, p);
		t5 = (t4 + t3) % p;
		answer = rcout(t5, p);

	The swap function exchanges the values of two variables without
	performing copies.  For example, after:

		x = 17;
		y = 19;
		swap(x, y);

	then x is 19 and y is 17.  This function should not be used to
	swap a value which is contained within another one.  If this is
	done, then some memory will be lost.  For example, the following
	should not be done:

		mat x[5];
		swap(x, x[0]);

	The hash function returns a relatively small non-negative integer
	for one or more input values.  The hash values should not be used
	across runs of the calculator, since the algorithms used to generate
	the hash value may change with different versions of the calculator.

	The base function allows one to specify how numbers should be
	printed.  The base function provides a numeric shorthand to the
	config("mode") interface.  With no args, base() will return the
	current mode.  With 1 arg, base(val) will set the mode according to
	the arg and return the previous mode.

	The following convention is used to declare modes:

		 base	 config
		value	 string

		   2	"binary"	binary fractions
		   8	"octal"		octal fractions
		  10	"real"		decimal floating point
		  16	"hex"		hexadecimal fractions
		 -10	"int"		decimal integer
		 1/3	"frac"		decimal fractions
		1e20	"exp"		decimal exponential

	For convenience, any non-integer value is assumed to mean "frac",
	and any integer >= 2^64 is assumed to mean "exp".
