Description:
Conversion functions for USD equivalents use native JS parseFloat and multipliers like 1e6. This causes rounding errors for large currency amounts.
How to Reproduce:
Call calculateBcUsdEquivalent with a very large amountFloat (e.g., 10^18 wei equivalent).
Actual Behaviour:
Resulting values lose precision after the 15th significant digit, which is unacceptable for financial software.
Expected Behaviour:
All currency calculations must stay within BigInt or a dedicated library like bignumber.js until the final display stage.
