- Field Detail
  - SMALLEST_UNIT_EXPONENT
```
public static final int SMALLEST_UNIT_EXPONENT
```
    Number of decimals for one Bitcoin. This constant is useful for quick adapting to other coins because a lot of constants derive from it.

  - SATOSHI
```
public static final Coin SATOSHI
```
    A satoshi is the smallest unit that can be transferred. 100 million of them fit into a Bitcoin.
  - FIFTY_COINS
```

```
  - NEGATIVE_SATOSHI
```

  - valueOf
```
public static Coin valueOf(long satoshis)
```
  - smallestUnitExponent
```
public int smallestUnitExponent()
```
    Description copied from interface: Monetary
    
    Returns the absolute value of exponent of the value of a "smallest unit" in scientific notation. For Bitcoin, a satoshi is worth 1E-8 so this would be 8.
    
    Specified by:
    
    smallestUnitExponent in interface Monetary
  - getValue
```
public long getValue()
```
    Returns the number of satoshis of this monetary value.
    
    Specified by:
    
    getValue in interface Monetary
  - valueOf
```
public static Coin valueOf(int coins,
                           int cents)
```
    Convert an amount expressed in the way humans are used to into satoshis.
  - parseCoin
```
public static Coin parseCoin(String str)
```
    Parses an amount expressed in the way humans are used to.
    
    This takes string in a format understood by BigDecimal.BigDecimal(String), for example "0", "1", "0.10", "1.23E3", "1234.5E-5".
