MonetaryFormat (bitcoinj 0.14 API)

java.lang.Object
- org.bitcoinj.utils.MonetaryFormat

```
public final class MonetaryFormat
extends Object
```
Utility for formatting and parsing coin values to and from human readable form.

MonetaryFormat instances are immutable. Invoking a configuration method has no effect on the receiving instance; you must store and use the new instance it returns, instead. Instances are thread safe, so they may be stored safely as static constants.

  - BTC
```
public static final MonetaryFormat BTC
```
    Standard format for the BTC denomination.
  - MBTC
```
public static final MonetaryFormat MBTC
```
    Standard format for the mBTC denomination.
  - UBTC
```
public static final MonetaryFormat UBTC
```
    Standard format for the µBTC denomination.
  - FIAT
```
public static final MonetaryFormat FIAT
```
    Standard format for fiat amounts.
  - CODE_BTC
```
public static final String CODE_BTC
```
    Currency code for base 1 Bitcoin.

  - CODE_MBTC
```
public static final String CODE_MBTC
```
    Currency code for base 1/1000 Bitcoin.

- Method Detail
  - negativeSign
```
public MonetaryFormat negativeSign(char negativeSign)
```
    Set character to prefix negative values.
  - positiveSign
```
public MonetaryFormat positiveSign(char positiveSign)
```
    Set character to prefix positive values. A zero value means no sign is used in this case. For parsing, a missing sign will always be interpreted as if the positive sign was used.
  - digits
```
public MonetaryFormat digits(char zeroDigit)
```
    Set character range to use for representing digits. It starts with the specified character representing zero.
  - decimalMark
```
public MonetaryFormat decimalMark(char decimalMark)
```
    Set character to use as the decimal mark. If the formatted value does not have any decimals, no decimal mark is used either.
  - minDecimals
```
public MonetaryFormat minDecimals(int minDecimals)
```
    Set minimum number of decimals to use for formatting. If the value precision exceeds all decimals specified (including additional decimals specified by optionalDecimals(int...) or repeatOptionalDecimals(int, int)), the value will be rounded. This configuration is not relevant for parsing.
  - optionalDecimals
```
public MonetaryFormat optionalDecimals(int... groups)
```
    Set additional groups of decimals to use after the minimum decimals, if they are useful for expressing precision. Each value is a number of decimals in that group. If the value precision exceeds all decimals specified (including minimum decimals), the value will be rounded. This configuration is not relevant for parsing.
    
    For example, if you pass 4,2 it will add four decimals to your formatted string if needed, and then add another two decimals if needed. At this point, rather than adding further decimals the value will be rounded.
    
    Parameters:
    
    groups - any number numbers of decimals, one for each group
  - repeatOptionalDecimals
```
public MonetaryFormat repeatOptionalDecimals(int decimals,
                                             int repetitions)
```
    Set repeated additional groups of decimals to use after the minimum decimals, if they are useful for expressing precision. If the value precision exceeds all decimals specified (including minimum decimals), the value will be rounded. This configuration is not relevant for parsing.
    
    For example, if you pass 1,8 it will up to eight decimals to your formatted string if needed. After these have been used up, rather than adding further decimals the value will be rounded.
    
    Parameters:
    
    decimals - value of the group to be repeated
    
    repetitions - number of repetitions
  - shift
```
public MonetaryFormat shift(int shift)
```
    Set number of digits to shift the decimal separator to the right, coming from the standard BTC notation that was common pre-2014. Note this will change the currency code if enabled.
  - roundingMode
```
public MonetaryFormat roundingMode(RoundingMode roundingMode)
```
    Set rounding mode to use when it becomes necessary.
  - noCode
```
public MonetaryFormat noCode()
```
    Don't display currency code when formatting. This configuration is not relevant for parsing.
  - code
```
public MonetaryFormat code(int codeShift,
                           String code)
```
    Configure currency code for given decimal separator shift. This configuration is not relevant for parsing.
    
    Parameters:
    
    codeShift - decimal separator shift, see shift
    
    code - currency code
  - codeSeparator
```
public MonetaryFormat codeSeparator(char codeSeparator)
```
    Separator between currency code and formatted value. This configuration is not relevant for parsing.
  - prefixCode
```
public MonetaryFormat prefixCode()
```
    Prefix formatted output by currency code. This configuration is not relevant for parsing.
  - postfixCode
```
public MonetaryFormat postfixCode()
```
    Postfix formatted output with currency code. This configuration is not relevant for parsing.
  - withLocale
```
public MonetaryFormat withLocale(Locale locale)
```
    Configure this instance with values from a Locale.
  - format
```
public CharSequence format(Monetary monetary)
```
    Format the given monetary value to a human readable form.
  - parse
```
public Coin parse(String str)
           throws NumberFormatException
```
    Parse a human readable coin value to a Coin instance.
    
    Throws:
    
    NumberFormatException - if the string cannot be parsed for some reason
  - parseFiat
```
public Fiat parseFiat(String currencyCode,
                      String str)
               throws NumberFormatException
```
    Parse a human readable fiat value to a Fiat instance.
    
    Throws:
    
    NumberFormatException - if the string cannot be parsed for some reason
  - code
```
public String code()
```
    Get currency code that will be used for current shift.
