Method bignum

src/compute-engine/index.ts:915–917

Create an arbitrary precision number. * * The return value is an object with methods to perform arithmetic * operations: * - `toNumber()`: convert to a JavaScript `number` with potential loss of precision * - `add()` * - `sub()` * - `neg()` (unary minus) * - `mul()` * -

(a: string | number | bigint | BigDecimal)

   * Declare a new type in the current scope.
   *
   * By default, types are nominal. To declare a structural type, set
   * `alias` to `true`.
   *
   * `fromStatement` marks the declaration as coming from a `DeclareType`
   * statement: such a declaration may be replaced by a later `DeclareType`
   * statement for the same name in the same scope (a re-run of the program).
