Should we use MPFR for new mathematics?
I'm not very familiar with it, but am I correct in understanding that this can
definitely represent a decimal number correctly, albeit a floating point number?
Regards.

Hi, Jordan
Thank you, that was an easy to understand explanation.
I would agree with that, if it means creating new math features that aren't
currently bundled, rather than unifying them with GMP.
How far along is this plan now? I'm very interested in that.
Regards.

been years since i checked, but last time i checked, BCMath supports
floating point numbers,
and PHP's GMP wrappers does not (this is not a limitation of GMP
itself, but of PHP's GMP wrappers)
- has the GMP api floating issues been fixed? a quick test suggest
/no/: https://3v4l.org/FQaI4

Hi, Claude
I'm very sorry, I'm not a native English speaker and I couldn't quite
understand whether you think BCMath should be integrated into GMP.
I understand your use case well, so if you don't mind, can I ask if it should
or should not be integrated?
Regards.

Hi, Jeff
Thanks for letting me know your use case.
This is important information when discussing this issue.

We use BCMath for money calculations.

Hi, Pierre
In fact, I predict that many use cases will be covered by GMP.
Still, I think that there may be cases where calculation functions like
mainframe BCD are required, such as when calculating money.
I am unable to decide whether it is correct to deprecate BCMath and only use
GMP.

Hi, Marc, Pierre
Thank you for all the information.
After all, I feel that BCMath and GMP have different roles.
Arbitrary precision mathematics and very high precision mathematics are similar
but distinctly different.
If PHP has already started integrating these things, then of course I'll fol

Hello,
Recently I was trying to fix and clean some of the stuff within the BCmath
extension along with Girgias who helped me. I wanted to enrich this
extension with similar functions that GMP contains and improve the
performance, however, I went to some conclusions and stopped it.

Hi, internals
I would like to start the discussion for my RFC "Adding bcround, bcfloor and
bcceil to BCMath”.
