Usage

To use the package in your Node.js project, import the addDecimal and removeDecimal functions:

const { addDecimal, removeDecimal } = require("decimal-token-processor");

// Example usage for adding decimals
const details = {
  chainId: 1,
  rpcProvider: "https://custom-rpc-provider-url.com", // Optional: Use custom RPC provider
  contractAddress: "0x...", // Provide the contract address for custom tokens; skip for native tokens
  value: 0.01, // Amount you want to convert
};

const addedValue = addDecimal(details);
console.log(`Added Decimals Result: ${addedValue}`);

// Example usage for removing decimals
const removedValue = removeDecimal({
  chainId: 1,
  rpcProvider: "https://custom-rpc-provider-url.com", // Optional: Use custom RPC provider
  contractAddress: "0x..", // Provide the contract address for custom tokens; skip for native tokens
  value: 1000000000, // Amount you want to convert
});

console.log(`Removed Decimals Result: ${removedValue}`);
