// Convert VESTS to HP
const vests = chain.vestsCoins(1000000);
const hp = chain.vestsToHp(vests, totalVestingFundHive, totalVestingShares);

const hpData = chain.getAsset(hp);
console.log(`1,000,000 VESTS = ${hpData.amount} ${hpData.symbol}`);

// Convert HP to VESTS
const hiveAmount = chain.hiveCoins(1000);
const vestsAmount = chain.hpToVests(hiveAmount, totalVestingFundHive, totalVestingShares);

const vestsData = chain.getAsset(vestsAmount);
console.log(`1,000 HP = ${vestsData.amount} ${vestsData.symbol}`);

// Get price feed
const feed = await chain.api.database_api.get_feed_history({});
const base = feed.current_median_history.base;
const quote = feed.current_median_history.quote;

// Convert HBD to HIVE
const hbd = chain.hbdCoins(100);
const hive = chain.hbdToHive(hbd, base, quote);

const hiveData = chain.getAsset(hive);
console.log(`100 HBD = ${hiveData.amount} ${hiveData.symbol}`);
