New Comment:
I agree that this should be fixed, but to my knowledge
run-tests.php does not support %E, but only %f. Are you using
another test runner?

Description:
------------
Many tests parse the result of var_dump() on a float and expect the result to
be an integer:

This is problematic because var_dump() will print sufficiently large numbers in
exponential notation. An example in Linux:
$ mkdir tmp
$ sudo mount -t tmpfs -o size=$((1 << 62)) tmpfs tmp
$ ~/src/php-src/sapi/cli/php --version
PHP 8.0.0-dev (cli) (built: Aug 25 2020 12:55:38) ( NTS )

Zend Engine v4.0.0-dev, Copyright (c) Zend Technologies
$ ~/src/php-src/sapi/cli/php -r 'var_dump(disk_total_space("tmp"));'
float(4.611686018427388E+18)
I think every instance of "float(%d)" in such tests could simply be converted
to use "float(%E)" instead.
