Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`int`	`getExponent()`	Exponent part of the associated factor in `base^exponent` representation.
`java.lang.String`	`getName()`	Returns the name of this prefix.
`java.lang.String`	`getSymbol()`	Returns the symbol of this prefix.
`java.lang.Number`	`getValue()`	Returns the value of this prefix.

- Method Detail
  - getName
```
java.lang.String getName()
```
    Returns the name of this prefix.
    
    Returns:
    
    this prefix name, not null.
  - getSymbol
```
java.lang.String getSymbol()
```
    Returns the symbol of this prefix.
    
    Returns:
    
    this prefix symbol, not null.
  - getValue
```
java.lang.Number getValue()
```
    Returns the value of this prefix. If the exponent is different from 1, this value is the base part of the associated factor in base^exponent representation.
    
    Returns:
    
    The prefix value.
  - getExponent
```
int getExponent()
```
    Exponent part of the associated factor in base^exponent representation. For different factors, e.g. rational numbers like 1/4 the exponent is always 1.
    
    Returns:
    
    the exponent part of this prefix.
