Divisor Continuity Adjustment

Install and import

bash
npm install fintech-algorithms
ts
import { calculate } from "fintech-algorithms/index-and-benchmark-engineering/index-initialization-and-continuity/divisor-continuity-adjustment";

Signature

calculate(data)

Worked example

verified This is the worked example published in the article, replayed by the test suite on every run. The output cannot drift.

Input

data
{
  "oldMarketValue": 100000000,
  "newMarketValue": 112000000,
  "oldDivisor": 100000
}

Call

calculate(data)

Returns

object with 4 fields: oldLevel, newDivisor, bridgedLevel, continuityError

{
  "oldLevel": 1000,
  "newDivisor": 112000,
  "bridgedLevel": 1000,
  "continuityError": 0
}

How it works

This page states the contract — how to call it correctly. The article explains the concept: why it works, and where it breaks.
