transaction value does not match signed transaction params in ethereumJS-TX

Question

I sign this transaction with Ethereumjs-tx:

{ 
    nonce: 8,
    gasPrice: 20,
    gasLimit: 25000,
    to: '0x45cc01d4b9ad49b81527d5b6629da8664bb525d3',
    value: 1000000,
    data: '0x00',
    chainId: 3 
}

however, the value on etherscan shows 0.013845257383850032 Ether

https://ropsten.etherscan.io/tx/0xa891e47b6fad75750a40d6ea2698fe409e4650c59acbc910eaa5cabe1169a4e0

Where doe the 0.0038xxxx extra ether come from?

Answer 1

Larger ints don't work well with ethereumJS-tx. If you have a large int, use

ethereumjs-util.intToBuffer()

or

new BN(value) to convert it to BN which seems to work as well.
