Niels Dossche bf3c4870b6 Avoid needless memsets by creating a variant of bc_new_num that doesn't memset (#14133)
Also avoid some memsets where we do call bc_new_num.

Saki Takamachi 1ae58d4784 ext/bcmath: Removed unnecessary zero padding (#14134)
bc_num is initialized to 0 by `memset`, so there is no need to write it to 0.

Niels Dossche a66439adbb Avoid unnecessary number initializations in BCMath (#14104)
Since freeing can deal with NULL, we can avoid calling bc_init_num and
avoid resetting the number during parsing.

Niels Dossche 3215e86a11 Avoid double allocation in _bc_new_num_ex
Since the two allocations are tied together anyway, we can just use a
single allocation. Moreover, this actually seemed like the intention
because the bc_struct allocation already accounted for the length and
scale.

Saki Takamachi 5d91f8761b Remove rscale in bc_raisemod
power is a copy of base and returns early if base->n_scale is non-zero. Since
scale is size_t, it is always greater than or equal to 0, so rscale is always
the value of scale.

Jorg Adam Sowa 6647d5f609 ext/bcmath: Remove debug.c file (#13359) 2024-02-09 11:29:57 +00:00
Jorg Adam Sowa e56ed6e1ab BCmath extension code reformatting (#11896)
Re-formats the BCmath extension to have consistent formatting.

Mostly, it adds the spaces in calculations to have them more readable.

Also:

   -  removes unused headers
   -  removes few variables which are used only once in the code

George Peter Banyard 68247c02d5 Refactor BCMath bundledlib and extension (#10774)
* ext/bcmath: coding style: use indentation

the sign.

Peter Kokot 1ad08256f3 Sync leading and final newlines in source code files
This patch adds missing newlines, trims multiple redundant final
newlines into a single one, and trims redundant leading newlines.

According to POSIX, a line is a sequence of zero or more non-' <newline>'
characters plus a terminating '<newline>' character. [1] Files should
normally have at least one final newline character.

C89 [2] and later standards [3] mention a final newline:
"A source file that is not empty shall end in a new-line character,
which shall not be immediately preceded by a backslash character."

Although it is not mandatory for all files to have a final newline
fixed, a more consistent and homogeneous approach brings less of commit
differences issues and a better development experience in certain text
editors and IDEs.
