public BigFraction(BigInteger num)
```
    Create a BigFraction equivalent to the passed BigInteger, ie "num / 1".
    
    Parameters:
    
    num - the numerator.
  - BigFraction
```
public BigFraction(BigInteger numIn,
                   BigInteger denIn)
```
    Create a BigFraction given the numerator and denominator as BigInteger. The BigFraction is reduced to lowest terms.
    
    Parameters:
    
    numIn - the numerator, must not be null.
    
    denIn - the denominator, must not be null.
    
    Throws:
    
    ZeroException - if the denominator is zero.

  - BigFraction
```
public BigFraction(double value)
```
    Create a fraction given the double value.
    This constructor behaves differently from BigFraction(double, double, int). It converts the double value exactly, considering its internal bits representation. This works for all values except NaN and infinities and does not requires any loop or convergence threshold.
    
    Since this conversion is exact and since double numbers are sometimes approximated, the fraction created may seem strange in some cases. For example, calling new BigFraction(1.0 / 3.0) does not create the fraction 1/3, but the fraction 6004799503160661 / 18014398509481984 because the double number passed to the constructor is not exactly 1/3 (this number cannot be stored exactly in IEEE754).
    
    Parameters:
    
    value - the double value to convert to a fraction.
    
    Throws:
    
    MathIllegalArgumentException - if value is NaN or infinite

    References:
    - Continued Fraction equations (11) and (22)-(26)
    Parameters:
    
    value - the double value to convert to a fraction.
    
    epsilon - maximum error allowed. The resulting fraction is within epsilon of value, in absolute terms.

  - reduce
```
public BigFraction reduce()
```
    Reduce this BigFraction to its lowest terms.
    
    Returns:
    
    the reduced BigFraction. It doesn't change anything if the fraction can be reduced.
  - subtract
```
public BigFraction subtract(BigInteger bg)
```
    Subtracts the value of an BigInteger from the value of this BigFraction, returning the result in reduced form.
    
    Parameters:
    
    bg - the BigInteger to subtract, cannot be null.
    
    Returns:
    
    a BigFraction instance with the resulting values.
    
    Throws:
    
    NullArgumentException - if the BigInteger is null.
  - subtract
```
public BigFraction subtract(int i)
```
    Subtracts the value of an integer from the value of this BigFraction, returning the result in reduced form.
    
    Parameters:
    
    i - the integer to subtract.
    
    Returns:
    
    a BigFraction instance with the resulting values.
  - subtract
```
public BigFraction subtract(long l)
```
    Subtracts the value of a long from the value of this BigFraction, returning the result in reduced form.
    
    Parameters:
    
    l - the long to subtract.
    
    Returns:
    
    a BigFraction instance with the resulting values.
  - subtract
```
public BigFraction subtract(BigFraction fraction)
```
    Subtracts the value of another fraction from the value of this one, returning the result in reduced form.
    
    Specified by:
    
    subtract in interface FieldElement<BigFraction>
    
    Parameters:
    
    fraction - BigFraction to subtract, must not be null.
    
    Returns:
    
    a BigFraction instance with the resulting values
    
    Throws:
    
    NullArgumentException - if the fraction is null.
  - toString
```
public String toString()
```
    Returns the String representing this fraction, ie "num / dem" or just "num" if the denominator is one.
    
    Overrides:
    
    toString in class Object
    
    Returns:
    
    a string representation of the fraction.
