Subject: Add bcround, bcfloor, bcceil to BCMath.
From: saki@sakiot.com (Saki Takamachi)

Hi, internals.

I'm currently working on renovating the `round()` function.

The current `round()` function rounds a value like 0.285 (0.28499....) to 0.=
29 using pre-round.
This is a mistake for FP, so discussions are underway to abolish such pre-ro=
und behavior.

However, there is definitely a user request to round 0.285 to 0.29, so I tho=
ught why not add a function similar to the round function to BCMath.

Similarly, I'm considering adding similar functionality to `floor()` and `ce=
il()`. In rare cases, when dealing with very large values, these will return=
 a different value than expected as a decimal number.

I would love to hear everyone's opinions.

Regards.
