```
public Decimal2f(String value)
```
    Translates the string representation of a Decimal into a Decimal2f. The string representation consists of an optional sign, '+' or '-' , followed by a sequence of zero or more decimal digits ("the integer"), optionally followed by a fraction.
    The fraction consists of a decimal point followed by zero or more decimal digits. The string must contain at least one digit in either the integer or the fraction. If the fraction contains more than 2 digits, the value is rounded using HALF_UP rounding. An exception is thrown if the value is too large to be represented as a Decimal2f.
    
    Parameters:
    
    value - String value to convert into a Decimal2f
    
    Throws:
    
    NumberFormatException - if value does not represent a valid Decimal or if the value is too large to be represented as a Decimal2f

  - valueOf
```
public static Decimal2f valueOf(String value)
```
    Translates the string representation of a Decimal into a Decimal2f. The string representation consists of an optional sign, '+' or '-' , followed by a sequence of zero or more decimal digits ("the integer"), optionally followed by a fraction.
    The fraction consists of a decimal point followed by zero or more decimal digits. The string must contain at least one digit in either the integer or the fraction. If the fraction contains more than 2 digits, the value is rounded using HALF_UP rounding. An exception is thrown if the value is too large to be represented as a Decimal2f.
    
    Parameters:
    
    value - String value to convert into a Decimal2f
    
    Returns:
    
    a Decimal2f calculated as: round_{HALF_UP}(value)
    
    Throws:
    
    NumberFormatException - if value does not represent a valid Decimal or if the value is too large to be represented as a Decimal2f

```
protected Decimal2f createOrAssign(long unscaled)
```
    Description copied from class: AbstractDecimal
    
    Returns this or a new Decimal whose value is (unscaled × 10^-scale).
    The returned value is a new instance if this decimal is an ImmutableDecimal. If it is a MutableDecimal then its internal state is altered and this is returned as result now representing (unscaled × 10^-scale).
    
    Specified by:
    
    createOrAssign in class AbstractDecimal<Scale2f,Decimal2f>
    
    Parameters:
    
    unscaled - unscaled value to be returned as a Decimal
    
    Returns:
    
    unscaled × 10^-scale
  - create
```
protected Decimal2f create(long unscaled)
```
    Description copied from class: AbstractDecimal
    
    Returns a new Decimal whose value is (unscaled × 10^-scale).
    
    Specified by:
    
    create in class AbstractDecimal<Scale2f,Decimal2f>
    
    Parameters:
    
    unscaled - unscaled value to be returned as a Decimal

    unscaled × 10^-scale
  - createArray

protected Decimal2f[] createArray(int length)
```
    Description copied from class: AbstractDecimal
    
    Returns a new Decimal array of the specified length.
    
    Specified by:
    
    createArray in class AbstractDecimal<Scale2f,Decimal2f>
    
    Parameters:
    
    length - the length of the array to return
    
    Returns:
    
    new D[length]
  - multiplyExact
```
public Multipliable2f multiplyExact()
```
    Returns this Decimal as a multipliable factor for typed exact multiplication. The second factor is passed to one of the by(..) methods of the returned multiplier. The scale of the result is the sum of the scales of this Decimal and the second factor passed to the by(..) method.
    The method is similar to multiplyExact(Decimal) but the result is retrieved in exact typed form with the correct result scale.
    For instance one can write:
```
 Decimal4f product = this.multiplyExact().by(Decimal2f.FIVE);
 
```
    Returns:
    
    a multipliable object encapsulating this Decimal as first factor of an exact multiplication
  - toMutableDecimal
```
public MutableDecimal2f toMutableDecimal()
```
    Description copied from interface: Decimal
    
    If this Decimal value is already a MutableDecimal it is simply returned. Otherwise a new mutable value with the same scale and numerical value as this Decimal is created and returned.
    
    Returns:
    
    this if mutable and a new MutableDecimal with the same scale and value as this Decimal otherwise
  - toImmutableDecimal
```
public Decimal2f toImmutableDecimal()
```
    Description copied from interface: Decimal
    
    If this Decimal value is already an ImmutableDecimal it is simply returned. Otherwise a new immutable value with the same scale and numerical value as this Decimal is created and returned.
    
    Returns:
    
    this if immutable and a new ImmutableDecimal with the same scale and value as this Decimal otherwise
