#num_precision_from_significant(num, significant, base) ⇒ Object

When base != 10 and the source is in E-notation, derive the target-base fractional digit count from the total significant digit count we computed. Plurimath's default precision_from() returns the decimal fractional digit count, which Numbers::Fraction#change_base then uses as the target-base fractional digit count -- producing too few fractional digits in non-decimal bases. Workaround pending upstream fix; see https://github.com/metanorma/isodoc/issues/788.

#num_totaldigits_compute(num, base) ⇒ Object

In base 10, total significant digits = source mantissa length. In other bases, the converted value may have fewer digits. Per https://github.com/metanorma/isodoc/issues/788: if the source has no fractional part after E-notation expansion, return the length of the integer in the target base (e.g. 123 -> 7B = 2 digits, not 3); if the source has a fractional part, preserve the source mantissa length so Plurimath pads the converted fraction (e.g. 123.25 -> 7B.400, 123.0 -> 7B.00).

#numberformat_unclassified_warn ⇒ Object

Union plurimath's option defaults against metanorma's known lists, and warn (once) on anything plurimath exposes that metanorma has not classified -- e.g. a passthrough option added upstream (potentially via a direct Peter Wyatt request) that we would otherwise be none the wiser of. DEFAULT_OPTIONS is the passthrough watch-point, not plurimath's entire option surface. See metanorma/basicdoc-models#35.
