Fixed the incorrect scale that should be used when dividing by 1, that is,
comparing the divisor and 1 to confirm equality.
Additionally, have increased the number of test cases for bcdiv_by_pow_10.phpt.
Add coverage for:
* different formats of zero (0, 0.0)
* small integers and decimals
* large integers and large decimals with large fractional part
* negative numbers for all of the above ones
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 adds missing newlines, trims multiple redundant final
newlines into a single one, and trims redundant leading newlines in all
*.phpt sections.
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.
