• base_convert read-only

  Converts a bounded integer string between bases 2 through 36 using exact BigInt arithmetic. Inputs contain 1–4096 digits and must be valid in the source base. Optional bitWidth (1–4096) validates a bit pattern; signed=true requires a width and reads the source value as two’s complement. Unsigned is the default.

  Parameters:

  • value (required) — string — Digits 0–9/A–Z without prefix, sign or separators; valid in fromBase.
  • fromBase (required) — integer
  • toBase (required) — integer
  • signed — boolean — Defaults to false. When true, interpret the fitting source bit pattern as two’s complement.
  • bitWidth — integer — Optional bit width; required when signed is true.

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• roman_numeral read-only

  Convert whole numbers from 1 to 3999 to canonical Roman numerals, or convert canonical Roman numerals to numbers.

  Parameters:

  • value (required) — string — Decimal whole-number text from 1–3999 for to_roman, or Roman numeral text in either case for from_roman.
  • direction (required) — string — Conversion direction.

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• round_sig_figs read-only

  Round a decimal string to a chosen number of significant figures using exact decimal half-up rounding; return plain and scientific notation.

  Parameters:

  • value (required) — string — Signed decimal string, optionally with exponent notation; no commas.
  • significantFigures (required) — integer — Number of significant figures to keep.
