CsvNumber (opencsv 5.1 API)

```
@Documented
@Retention(RUNTIME)
@Target(FIELD)
public @interface CsvNumber
```
This annotation indicates that the destination field is a number that is specially formatted. Numbers that have no more formatting than that which comes with a locale (or the default locale) do not require this annotation. If a locale is specified in the attendant CSV binding annotation (CsvBindByName, CsvBindByPosition, etc.), it is used for the conversion. The following types are supported:
- byte / Byte
- double / Double
- float / Float
- int / Integer
- long / Long
- short / Short
- BigDecimal
- BigInteger

java.lang.String value
```
    A decimal format string. This must be a localized pattern understood by DecimalFormat. The locale is gleaned from one of the other CSV-related annotations if present there, or failing that, is the default locale for the JVM. If your code might run under different locales, you are strongly encouraged to always specify a locale for conversions, otherwise your code will behave unpredictably.
    
    Returns:
    
    The format string for parsing input
- - writeFormatEqualsReadFormat
```
boolean writeFormatEqualsReadFormat
```
    Whether or not the same format string is used for writing as for reading. If this is true, value() is used for both reading and writing and writeFormat() is ignored.
    
    Returns:
    
    Whether the read format is used for writing as well
