I see that 'cent' and 'ucent' are reserved for future use but not yet implemented. Does anyone have a working implementation of these types?

Alternatively, is there an any effort towards implementation of arbitrary-sized integers in Phobos?

Thanks,
Saurabh

There is BigInt in phobos.

The keywords are reserved for future use not in current use. So, no, there are no 128-bit integer types in D currently. It's just that we left the door open for ourselves to add them later without breaking programs due to having to create a new keyword.

We've had that for years. It's BigInt in std.bigint.

Thankyou. I'll have a look at that.

I think cent and ucent could be implemented as ulong is possible to be used on 32-bit systems by adding extra assembly instructions. This way, when (and if) 128-bit systems are developed, compiler would be updated only.

There is a recursive arbitrary sized integer implementation floating around somewhere. Perhaps try dub for some math libraries.

wideint was exactly what I was looking for! Thank you so much :)

 I WANT! If this does the job, I want it as part of the Phobos library!!

This request again ;)
I don't know how this works, someone has to propose it, clean it up and respond to feedback I guess.
