- 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.

    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".
    
    Throws:
    
    IllegalArgumentException - if you try to specify fractional satoshis, or a value out of range.

```
  - subtract
```
public Coin subtract(Coin value)

  - isNegative
```
public boolean isNegative()
```
    Returns true if and only if this instance represents a monetary value less than zero, otherwise false.
  - isZero
```
public boolean isZero()
```
    Returns true if and only if this instance represents zero monetary value, otherwise false.
  - isGreaterThan
```
public boolean isGreaterThan(Coin other)
```
    Returns true if the monetary value represented by this instance is greater than that of the given other Coin, otherwise false.
  - isLessThan
```
public boolean isLessThan(Coin other)
```
    Returns true if the monetary value represented by this instance is less than that of the given other Coin, otherwise false.
  - shiftLeft
```
public Coin shiftLeft(int n)
```
  - shiftRight
```
public Coin shiftRight(int n)
```
  - signum
```
public int signum()
```
    Specified by:
    
    signum in interface Monetary
  - negate
```
public Coin negate()
```
  - longValue
```
public long longValue()
```
    Returns the number of satoshis of this monetary value. It's deprecated in favour of accessing value directly.
  - toFriendlyString
```
public String toFriendlyString()
```
    Returns the value as a 0.12 type string. More digits after the decimal place will be used if necessary, but two will always be present.
  - toPlainString
```
public String toPlainString()
```
    Returns the value as a plain string denominated in BTC. The result is unformatted with no trailing zeroes. For instance, a value of 150000 satoshis gives an output string of "0.0015" BTC
