`npx oz send-tx --value 1e17` transfers 0.000000000000007703 Ether

[abcoathup]

Reported by Gökhan Çoban in Telegram attempting to send a transaction with value 0.1 ether to a contract.

If 1e17 is an invalid number format the command should fail. If 1e17 is supported then 0.1 Ether should be sent.

1e17 is being parsed as Hex so is treated as 7703 (thanks to Anatol in Telegram)
