17727, "lydiaduncan", "[Library Stabilization] Should the argument names for these BigInteger methods be longer?", "20210513T18:57:28Z"
The arguments for divexact
, divisible_p
, divisible_2exp_p
, congruent_p
and congruent_2exp_p
are a single character long. The letter used is descriptive (n for numerator, d for divisor and denominator, c for congruent, b for base), but it seems like having a longer argument name would be more friendly.
Do others agree?
If so, I'd like to propose:

bigint.divexact(numer, denom)
(To avoid confusion with num for number) bigint.divisible_p(div)
bigint.divisible_2exp_p(exp)
bigint.congruent_p(con, mod)
bigint.congruent_2exp_p(con, modExp)
You can find these function descriptions here: Integer Division (GNU MP 6.2.1)
(We talk about the names of the methods themselves in #17724 so I'm not going to have those changed here for clarity)
