The following are the changes in this release:
Starting with calc version 2.16.0.0, the ability to perform arithmetic
on addresses of values in calc objects has been greatly restricted.
Most arithmetic on of value addresses could easily cause calc to
crash. For example, prior to calc version 2.16.0.0, the following
command was likely to crash calc:
calc '*((&.)+1e9)'
Subtracting two value addresses is permitted, however there is NO
guarantee that the address of a value will remain consistent across
calc runs. Addresses of values depend on the circumstances of when
the calc values were formed.
The above restrictions and caveats apply to addresses of values.
Such restrictions and caveats to NOT apply to the addresses of
octets, NOR to the addresses within strings. If isptr(x) == 2, then
x is value-pointer and the above mentioned restrictions and caveats apply.
See "help address" for more information on value address arithmetic.
Added E_INVALID_DEREF (10610) error code to indicate the invalid
dereferencing a non-variable.
Added E_INVALID_ADDR_OP (10611) error code to indicate an invalid
arithmetic address operation.
We plan to let this most recent change settle down before performing
the calc v2 to calc v3 fork. Therefore, version 2.16.1.0 will form
the basis for the calc v2 to calc v3 fork.

|
* MAJOR_VER
|
|
*
|
|
* The MAJOR_VER is 2 is the classical version of calc.
|
|
*
|
|
* One of the main reasons why MAJOR_VER might incremented is
|
|
* if fundamental calc data objects (such as when ZVALUE or NUMBER
|
|
* or COMPLEX need to change) that would cause an incompatibility
|
|
* with existing hardware accelerators that are using fundamental
|
|
* calc data objects.
|
|
*
|
|
* MINOR_VER
|
|
*
|
|
* The MINOR_VER changes when there are incompatible changes to the calc library
|
|
* or calc custom library. The MINOR_VER might change if we need to make a major
|
|
* change to the math engine. For example, when the way 0^x was evaluated, we
|
|
* changed MINOR_VER from 13 to 14.
|
|
*
|
|
* MAJOR_PATCH
|
|
*
|
|
* The MAJOR_PATCH changes when there is an update to the calc library
|
|
* or calc custom library. For example, the MAJOR_PATCH might increment when there
|
|
* are new builtin functions available, or when there is a change to how existing
|
|
* builtin functions process arguments.
|
|
*
|
|
* MINOR_PATCH
|
|
*
|
|
* The MINOR_PATCH changes whenever there is any change in the calc release.
|
|
* For example, when the documentation changes, the MINOR_PATCH will increment.
|
|
* Moreover, when we are working towards a new production release,
|
|
* bug fix and improvement updates will cause MINOR_PATCH to increment.
