decimal provides arbitrary-precision decimal vectors for R backed by the
vendored mpdecimal C library.
Details
The package follows a three-part model:
immutable decimal values stored as exact strings;
an active arithmetic context controlling precision, rounding, exponent limits, traps, and sticky flags; and
vector semantics implemented with
vctrs.
Version 0.1.0 is a correctness-first release. It supports exact
construction, context-aware arithmetic, comparison, summaries, special
values, and tibble/data-frame use. Some advanced Python decimal
capabilities remain deferred and are documented in the package README and
vignettes.
