  A simple calculator that understands Bitcoin Units

  Basic example

    $ bcalc 1 msat + 2 sats + 3 bits to msats

    302001 msats

  BTC to satoshis

    $ bcalc 0.02 BTC

    2000000 sats

  satoshis to millisatoshis (for payment channels), also dont print unit

    $ bcalc --no-unit 100 sat to msats

    100000

  mBTC + bits to BTC

    $ bcalc 100 mBTC + 20 bits to btc

    0.10002 BTC

  Division

    $ bcalc 1 BTC / 100 to bits

    10000 bits

  Multiplication

    $ bcalc '10 mbtc * 30 to bits'

    300000 bits

  Fiat currencies
