sendTransaction sends unexpected amount of ether

[tinybike]

I'm attempting to send ether via the geth console, started with geth --rpc --rpccorsdomain "http://127.0.0.1:8545" --unlock primary console:

eth.sendTransaction({
    from: "0x63524e3fe4791aefce1e932bbfb3fdf375bfad89",
    to: "0x1c11aa45c792e202e9ffdc2f12f99d0d209bef70",
    value: "100000000000000000000"}
);

But when I look up the transaction hash, I've only sent 7.76 ether!

{
  hash: '0xac4139e6a805ba4d9523370cd4da042722f63ae097867c0b5faf694cc9d39f1a',
  nonce: '0x6',
  from: '0x63524e3fe4791aefce1e932bbfb3fdf375bfad89',
  to: '0x1c11aa45c792e202e9ffdc2f12f99d0d209bef70',
  gas: 90000,
  input: '0x',
  blockHash: '0xfbc1a79623f9d220d52f0f0a675a2495d9ba01b58b3def108c26cfa04db49178',
  blockNumber: 137480,
  transactionIndex: 0,
  value: '7766279631452241920',
  gasPrice: '10000000000000'
}

I've also tried using BigNumber.toString (base-10 and hex), both with the same result. Any idea what's going on here?

Update: as per @zelig's suggestion I tried using web3.toWei, which works for small amounts (I tested web3.toWei(0.00001, "ether"), which worked fine). However, when I attempt to send a larger amount (100 ether), I get the same issue:

> eth.sendTransaction({
..    from: "0x63524e3fe4791aefce1e932bbfb3fdf375bfad89",
..    to: "0x1c11aa45c792e202e9ffdc2f12f99d0d209bef70",
..    value: web3.toWei(100, "ether")
..  });
'0xf067aa5af29c3a1e4fdd5cc7213d800079a67cd06b515ad5639f7b3e0742192e'

> eth.getTransaction("0xf067aa5af29c3a1e4fdd5cc7213d800079a67cd06b515ad5639f7b3e0742192e")
{
  value: '7766279631452241920',
  gas: 90000,
  gasPrice: '10000000000000',
  input: '0x',
  nonce: '0x15',
  blockNumber: 137601,
  from: '0x63524e3fe4791aefce1e932bbfb3fdf375bfad89',
  to: '0x1c11aa45c792e202e9ffdc2f12f99d0d209bef70',
  hash: '0xf067aa5af29c3a1e4fdd5cc7213d800079a67cd06b515ad5639f7b3e0742192e',
  blockHash: '0xa168c3e6cbf2bf0ca9dc4806063279f79e7d593037b063b3c3d26561f919c1e0',
  transactionIndex: 0
}

7.76 ether again. Maybe this is a BigNumber issue?

It's a conversion error in the JSON RPC.

@tgerring When giving values greater than 2^64 (very likely) the int in numString will overflow. The same goes for:

• gas
• gasPrice
• value

The problem is in eth_transact and eth_call using NewTxArgs. big.Int is very good at parsing numbers and you really don't need to do any conversion yourself if you'd just accept string only.
