http://git.php.net/?p=php-src.git;a=blob_plain;f=UPGRADING;hb=refs/heads/PHP-7.2
has this to say on `bcmod()`:

> The `bcmod()` function no longer truncates fractional numbers
> to integers. As such, its behavior now follows `fmod()` rather than
> the `%` operator. For example `bcmod('4', '3.5')` now returns '0.5'
> instead of '1'.

However, I cannot reproduce this:

$ php --version
PHP 7.2.0 (cli) (built: Nov 28 2017 20:05:12) ( NTS )
Copyright (c) 1997-2017 The PHP Group
Zend Engine v3.2.0, Copyright (c) 1998-2017 Zend Technologies

$ php -r 'var_dump(bcmod('4', '3.5'));'
string(1) "0"

Am I missing something?

Thanks!
Sebastian

As usual, the results depend on the scale factor (which is 0 by
default); see <https://3v4l.org/cvvoa>.
