Floating-point arithmetic causes financial calculation errors due to binary precision loss. You fix it by enforcing decimal arithmetic using decimal.js or bignumber.js to maintain strict mathematical correctness and prevent inaccuracies in prices, volumes, and PnL.

You validate VWAP calculation accuracy by applying decimal arithmetic and strict mathematical invariants to your trading data. This ensures volume-weighted average prices are computed with absolute precision and remain fully auditable.

Yes, you need either decimal.js or bignumber.js to ensure mathematical correctness in financial systems. These dependencies are required to execute the decimal arithmetic operations necessary for validating prices, volumes, and PnL without floating-point inaccuracies.

The best way to track financial calculations for audit purposes is to enforce strict mathematical rules and decimal arithmetic. This provides a structured validation process that ensures precision and auditability for prices, volumes, and PnL metrics.

Yes, you can use decimal arithmetic to validate PnL and other financial metrics. By enforcing strict rules for mathematical operations, this approach prevents inaccuracies and ensures determinism across systems dealing with prices, volumes, and profit and loss.
