[PHP-DEV] bcmod() behavior is different from what I expected

Hi internals,

I noticed that `bcmod()` behavior is a little different from what I expected.

First, look at the following code for `bcdiv()`:

bcdiv('99', '100', 2); // '0.99'

So what should the following code be?

bcmod('99', '100', 2);

The result is `'99.00'`.
I was expecting `'0.00'` for this. I thought that if gave `bcdiv()` and `bcmod()` the exact same arguments, their results would not contradict each other.

To me this is unexpected behaviour, how do you think?

However, considering the behavior of `fdiv()` and `fmod()`, the current behavior of `bcmod()`may be correct and my thinking may be wrong...

I was probably tired. Please forget about this thread...
