Added BcMath\Number class. It is an immutable object, has methods that are
equivalent to existing BCMath calculation functions, and can also be calculated
using operators.
The existing BCMath function returned a string for each calculation, but this
class returns an object.

In the original specification, the scale of bc_num was directly changed
and compared.
This becomes a problem when objects are supported, so we will modify it
to compare without changing bc_num.
* Include from build dir first
This fixes out of tree builds by ensuring that configure artifacts are included
from the build dir.
Before, out of tree builds would preferably include files from the src dir, as
the include path was defined as follows (ignoring includes from ext/ and sapi/) :
-I$(top_builddir)/main
-I$(top_srcdir)
-I$(top_builddir)/TSRM
-I$(top_builddir)/Zend
-I$(top_srcdir)/main
-I$(top_srcdir)/Zend
-I$(top_srcdir)/TSRM
-I$(top_builddir)/
As a result, an out of tree build would include configure artifacts such as
`main/php_config.h` from the src dir.
After this change, the include path is defined as follows:
-I$(top_builddir)/main
-I$(top_builddir)
-I$(top_srcdir)/main
-I$(top_srcdir)
-I$(top_builddir)/TSRM
-I$(top_builddir)/Zend
-I$(top_srcdir)/Zend
-I$(top_srcdir)/TSRM
* Fix extension include path for out of tree builds
* Include config.h with the brackets form
`#include "config.h"` searches in the directory containing the including-file
before any other include path. This can include the wrong config.h when building
out of tree and a config.h exists in the source tree.
Using `#include <config.h>` uses exclusively the include path, and gives
priority to the build dir.
Using SIMD to accelerate the validation.

Since freeing can deal with NULL, we can avoid calling bc_init_num and
avoid resetting the number during parsing.

* ext/bcmath: coding style: use indentation
And add braces to block statements, as the current code was pretty much unreadable with how inconsistent it was.
* ext/bcmath: Remove some useless header inclusions
* ext/bcmath: Use standard C99 bool type instead of char
* ext/bcmath: Include specific headers instead of config.h
* Restructure definitions to reduce header inclusions
* Use size_t as a more appropriate type
* Remove unused variable full_scale
* Refactor bc_raisemod() to get rid of Zend dependencies
This separates the concerns of throwing exceptions back into the PHP_FUNCTION instead of being the responsibility of the library
* Refactor bc_raise() to get rid of Zend dependencies
This separates the concerns of throwing exceptions back into the PHP_FUNCTION instead of being the responsibility of the library
* Refactor bc_divmod() and bc_modulo() to return bool
Return false on division by 0 attempt instead of -1 and true on success instead of 0
* Refactor bc_divide() to return bool
Return false on division by 0 attempt instead of -1 and true on success instead of 0
Add zend_ini_parse_quantity() and deprecate zend_atol(), zend_atoi()
zend_atol() and zend_atoi() don't just do number parsing.
They also check for a 'K', 'M', or 'G' at the end of the string,
and multiply the parsed value out accordingly.
Unfortunately, they ignore any other non-numerics between the
numeric component and the last character in the string.
This means that numbers such as the following are both valid
and non-intuitive in their final output.
* "123KMG" is interpreted as "123G" -> 132070244352
* "123G " is interpreted as "123 " -> 123
* "123GB" is interpreted as "123B" -> 123
* "123 I like tacos." is also interpreted as "123." -> 123
Currently, in php-src these functions are used only for parsing ini values.
In this change we deprecate zend_atol(), zend_atoi(), and introduce a new
function with the same behavior, but with the ability to report invalid inputs
to the caller. The function's name also makes the behavior less unexpected:
zend_ini_parse_quantity().

1. Update: http://www.php.net/license/3_01.txt to https, as there is anyway server header "Location:" to https.
2. Update few license 3.0 to 3.01 as 3.0 states "php 5.1.1, 4.1.1, and earlier".
3. In some license comments is "at through the world-wide-web" while most is without "at", so deleted.
4. fixed indentation in some files before |
We're starting to see a mix between uses of zend_bool and bool.
Replace all usages with the standard bool type everywhere.
Of course, zend_bool is retained as an alias.
This converts the remaining "non well-formed" warnings in bcmath
to ValueErrors, in line with the other warning promotions that
have been performed in this extension.
Closes GH-80545.
We should keep the value of bcmath.scale and the internal
bc_precision global synchronized.
Probably more important than the ability to retrieve bcmath.scale
via ini_get(), this also makes sure that the set scale does not
leak into the next request, as it currently does.
Make sure bcmatch scale is between 0 and INT_MAX, both for the
ini setting, and all the functions accepting a scale argument.
A ValueError is thrown if a function argument is out of range.
Closes GH-5455.
`bcdiv()` and `bcmod()` throw DivisionByZeroError if the divisor is 0,
which matches the behavior of the `/` and `%` operators, and `bcsqrt()`
throws ValueError for negative operands.
This patch removes the so called local variables defined per
file basis for certain editors to properly show tab width, and
similar settings. These are mainly used by Vim and Emacs editors
yet with recent changes the once working definitions don't work
anymore in Vim without custom plugins or additional configuration.
Neither are these settings synced across the PHP code base.
A simpler and better approach is EditorConfig and fixing code
using some code style fixing tools in the future instead.
This patch also removes the so called modelines for Vim. Modelines
allow Vim editor specifically to set some editor configuration such as
syntax highlighting, indentation style and tab width to be set in the
first line or the last 5 lines per file basis. Since the php test
files have syntax highlighting already set in most editors properly and
EditorConfig takes care of the indentation settings, this patch removes
these as well for the Vim 6.0 and newer versions.
With the removal of local variables for certain editors such as
Emacs and Vim, the footer is also probably not needed anymore when
creating extensions using ext_skel.php script.
Additionally, Vim modelines for setting php syntax and some editor
settings has been removed from some *.phpt files. All these are
mostly not relevant for phpt files neither work properly in the
middle of the file.
The $Id$ keywords were used in Subversion where they can be substituted
with filename, last revision number change, last changed date, and last
user who changed it.
In Git this functionality is different and can be done with Git attribute
ident. These need to be defined manually for each file in the
.gitattributes file and are afterwards replaced with 40-character
hexadecimal blob object name which is based only on the particular file
contents.
This patch simplifies handling of $Id$ keywords by removing them since
they are not used anymore.
This function has been removed in 870ed5106d,
because it is not necessary to manipulate the `bc_num` itself; instead
we simply omit extraneous decimals when converting the number to
string.
This resolves the issue introduced by 24fd49fbab
in a cleaner way than 121d193514.
