While we might never be able to have 100% of our code strict, we can at
the very least do it for all of our tests. This ensures that our tests
are using our API with the types as intended by the test author, and not
silently be cast to what our API requires.
And quite a bit more manual changes. The idea is that typing of our
tests can be a bit more loose, so we assume PHPDoc is mostly correct. If
that happens to be wrong, it should be caught by the tests themselves.
Successor to PR #3523. There are 494 single-line changes (`public function provider` to `public static function provider`) in this PR. None of these were made manually; they were all created with the following script (adapted from
https://stackoverflow.com/questions/25909820/how-to-recursively-iterate-through-files-in-php):
```php
$dir = 'C:/git/unit10prep2/tests/PhpSpreadsheetTests';
$it = new RecursiveDirectoryIterator($dir);
// Loop through files
foreach(new RecursiveIteratorIterator($it) as $file) {
if ($file->getExtension() === 'php') {
$contents = file_get_contents($file);
$new = preg_replace('/public function (\\w*)([Pp])rovider/', 'public static function $1$2rovider', $contents);
if ($new !== $contents) {
echo "changing $file\n";
file_put_contents($file, $new);
}
}
}
```
After this PR, there will be one more, with a small number of test changes, and enabling PhpUnit 10 for Php 8.1+.
* Enable array-readiness for more Math/Trig functions; CEILING() FLOOR() (and variants), TRUNC(), BASE() and the various Logarithms
* Minor refactoring
* Continue MathTrig Breakup - Penultimate?
Continuing the process of breaking MathTrip.php up into smaller classes. This round takes care of about half of what is left, so perhaps one round after this one will finish the job:
- ARABIC
- COMBIN; also implemented COMBINA
- FACTDOUBLE
- GCD (which accepts and ignores empty cells as arguments, but returns VALUE if all the arguments are that way; LCM does the same)
- LOG_BASE, LOG10, LN
- implemented MUNIT
- MOD
- POWER
- RAND, RANDBETWEEN (RANDARRAY is too complicated to implement with this ticket)
As you can see from the description, there are some functions which were combined in a single class. When not combined, I adopted PowerKiki's suggestion of using "execute" as the function name.

* Problems Using Builtin PHP Functions Directly As Excel Functions
This fixes issue #1789.
As originally reported, stricter typing was causing PHP8 to throw
an exception when a non-numeric value was passed to the Round function.
Previous releases of PHP did not see this problem, however, on further
analysis, they were also incorrect in returning 0 as the result in the
erroneous situation, when they should have been returning a VALUE error.
Yet more analysis showed that other functions would also have problems,
and, in addition, might not handle invalid input (e.g. a negative length
passed to REPT) or output (e.g. NAN in the case of ACOS(2)) correctly.
The following MathTrig functions are affected:
ABS, ACOS, ACOSH, ASIN, ASINH, ATAN, ATANH,
COS, COSH, DEGREES (rad2deg), EXP, LN (log), LOG10,
RADIANS (deg2rad), REPT (str_repeat), SIN, SINH, SQRT, TAN, TANH.
One TextData function (REPT) is also affected.
This change lets PhpSpreadsheet validate the input for each of these
functions before passing control to the builtin, and handle the output
afterwards.
There were no explicit tests for any of these functions, a fact made
easy to ignore by the fact that PhpSpreadsheet delegated the heavy
lifting to PHP itself for these cases. A full suite of tests is
now added for each of the affected functions.
* Scrutinizer Recommendations
Only in 3 modules which are part of this PR.
* Improved Handling of Tan(PI/2)
Return DIV0 error for TAN when COS is very small.
* Additional Trig Tests
Results which should be infinity, i.e. DIV/0 error.
