no other compile errors, only the unterminated comment will stop
completion of the function being defined.
Added the reading of more calc resource files to the cal/regress.cal
regression test.
The issq() test had a slight performance boost. A minor note
was added to the help/issq file.
Improved the documentation of the mul2, sq2, pow2, and redc2 config
parameters in help/config.
Added config("baseb"), a read-only configuration value to return
the number of bits in the fundamental base in which calculations
are performed. This is a read-only configuration value.
Calc now permits such as:
++*p-- ++*----*++p----
where p is an lvalue; successful evaluation of course require the
successive operations to be performed to have operands of appropriate
types; e.g. in *A, A is usually an lvalue whose current value is a
pointer. ++ and -- act on lvalues. In the above examples there are
implied parentheses from the beginning to immediately after p. If
there are no pre ++ or -- operations, as in
**p++
the implied parentheses are from immediately before p to the end.
Improved the error message when && is used as a prefix operator.
Changed the help/config file to read like a builtin function
help file.
One can no longer set to 1, or to a value < 0, the config()
parameters: "mul2", "sq2", "pow2", and "redc2". These values
in the past would result in improper configuration of internal
calc algorithms. Changed cal/test4100.cal to use the minimal
value of 2 for "pow2", and "redc2".
Changed the default values for the following config() parameters:
config("mul2") == 1780
config("sq2") == 3388
config("pow2") == 176
These values were determined established on a 1.8GHz AMD 32-bit
CPU of ~3406 BogoMIPS by the new resource file:
cal/alg_config.cal
Regarding the alg_config.cal resource file:
The best_mul2() function returns the optimal value of config("mul2").
The best_sq2() function returns the optimal value of config("sq2").
The best_pow2() function returns the optimal value of config("pow2").
The other functions are just support functions.
By design, best_mul2(), best_sq2(), and best_pow2() take a few
minutes to run. These functions increase the number of times a
given computational loop is executed until a minimum amount of CPU
time is consumed. To watch these functions progress, one can set
the config("user_debug") value.
Here is a suggested way to use the alg_config.cal resource file:
; read alg_config
; config("user_debug",2),;
; best_mul2(); best_sq2(); best_pow2();
; best_mul2(); best_sq2(); best_pow2();
; best_mul2(); best_sq2(); best_pow2();
NOTE: It is perfectly normal for the optimal value returned
to differ slightly from run to run. Slight variations due to
inaccuracy in CPU timings will cause the best value returned to
differ slightly from run to run.
See "help resource" for more information on alg_config.cal.
Updated the "help variable" text to reflect the current calc
use of ` (backquote), * (star), and & (ampersand).

These functions search for an optimal value of config("mul2"),
config("sq2"), and config("pow2"). The calc default values of these
configuration values were set by running this resource file on a
1.8GHz AMD 32-bit CPU of ~3406 BogoMIPS.
The best_mul2() function returns the optimal value of config("mul2").
The best_sq2() function returns the optimal value of config("sq2").
The best_pow2() function returns the optimal value of config("pow2").
The other functions are just support functions.
By design, best_mul2(), best_sq2(), and best_pow2() take a few
minutes to run. These functions increase the number of times a
given computational loop is executed until a minimum amount of CPU
time is consumed. To watch these functions progress, one can set
the config("user_debug") value.
Here is a suggested way to use this resource file:
; read alg_config
; config("user_debug",2),;
; best_mul2(); best_sq2(); best_pow2();
; best_mul2(); best_sq2(); best_pow2();
; best_mul2(); best_sq2(); best_pow2();
NOTE: It is perfectly normal for the optimal value returned to differ
slightly from run to run. Slight variations due to inaccuracy in
CPU timings will cause the best value returned to differ slightly
from run to run.
One can use a calc startup file to change the initial values of
config("mul2"), config("sq2"), and config("pow2"). For example one
can place into ~/.calcrc these lines:
config("mul2", 1780),;
config("sq2", 3388),;
config("pow2", 176),;
to automatically and silently change these config values.
See help/config and CALCRC in help/environment for more information.

the choice from possible alternative algorithms, and whether or not
debugging information is displayed. The parameters are

second algorithm begins to be used. The minimum value is 2, and
the maximum value is very large. If 2 is used, then the recursive
algorithm is used all the way down to single digits, which becomes
slow since the recursion overhead is high. If a number such as

calculations for large numbers to slow down. For a typical example
on a 386, the two algorithms are about equal in speed for a value
of 20, which is about 100 decimal digits. A value of zero resets
the parameter back to its default value. Usually there is no need

base 2^32 with digits that are 32 bits in length.
For libcalc programmers, this is the value of BASEB as defined
in the zmath.h header file.
This config parameter is read-only and cannot be set.

One kind of use is to slow down output to permit easier reading of
results, as in:
> for (i = 0; i < 100; i++) {
print sqrt(i);
sleep(1/2);
}
; for (i = 0; i < 100; i++) {

There are no pointers in the calculator language, thus all
arguments to user-defined functions are normally passed by value.
This is true even for matrices, strings, and lists. In order
to circumvent this, the '&' operator is allowed before a variable
when it is an argument to a function. When this is done, the
address of the variable is passed to the function instead of its
value. This is true no matter what the type of the variable is.
This allows for fast calls of functions when the passed variable
is huge (such as a large array). However, the passed variable can
then be changed by the function if the parameter is assigned into.
The function being called does not need to know if the variable
is being passed by value or by address.
When working with user-defined functions, the syntax for passing an
lvalue by reference rather than by value is to precede an expression
for the lvalue by a backquote. For example, if the function invert is
defined by:
Built-in functions and object functions always accept their
arguments as addresses, thus there is no need to use '&' when
calling built-in functions.
define invert(x) {x = inverse(x)}
## Copyright (C) 1999 Landon Curt Noll
then invert(`A) achieves the effect of A = inverse(A). In other
words, passing and argument of `variable (with a back-quote)
will cause and changes to the function argument to be applied to
the calling variable. Calling invert(A) (without the ` backquote)
assigns inverse(A) to the temporary function parameter x and leaves
A unchanged.
In an argument, a backquote before other than an lvalue is ignored.
Consider, for example:
; define logplus(x,y,z) {return log(++x + ++y + ++z);}
; eh = 55;
; mi = 25;
; answer = logplus(eh, `mi, `17);
; print eh, mi, answer;
55 26 2
The value of eh is was not changed because eh was used as
an argument without a back-quote (`). However, mi was incremented
because it was passed as `mi (with a back-quote). Passing 17
(not an lvalue) as `17 has not effect on the value 17.
The back-quote should only be used before arguments to a function.
In all other contexts, a backquote causes a compile error.
Another method is to pass the address of the lvalue explicitly and
use the indirection operator * (star) to refer to the lvalue in the
function body. Consider the following function:
; define ten(a) { *a = 10; }
; n = 17;
; ten(n);
; print n;
17
; ten(`n);
; print n;
17
; ten(&n);
; print n;
10
Passing an argument with a & (ampersand) allows the tenmore()
function to modify the calling variable:
; wa = tenmore(&vx);
; print vx, wa;
65 65
Great care should be taken when using a pointer to a local variable
or element of a matrix, list or object, since the lvalue pointed to
is deleted when evaluation of the function is completed or the lvalue
whose value is the matrix, list or object is assigned another value.
As both of the above methods (using & arguments (ampersand) *value
(star) function values or by using ` arguments (back quote) alone)
copy the address rather than the value of the argument to the function
parameter, they allow for faster calls of functions when the memory
required for the value is huge (such as for a large matrix).
As the built-in functions and object functions always accept their
arguments as addresses, there is no gain in using the backquote when
calling these functions.
