  - EQUAL
```
public static final Function EQUAL
```
    Equality function.
    The test is performed using a threshold given by Operator.BOOLEAN_THRESHOLD.
    
    This function has two argument equal(a, b) where:
    
    a: First value to test
    
    b: Second value to test
    Since:
    
    0.6-riddler
    
    See Also:
    
    Operator.BOOLEAN_THRESHOLD
  - IF
```
public static final Function IF
```
    Branching function.
    This function has three argument if(exp, v_true, v_false) where:
    
    exp: Boolean expression
    
    v_true: Value if true
    
    v_false: Value if false
    Since:
    
    0.6-riddler

  - INFINITY
```
public static final Function INFINITY
```
    Retrieves the value of Double.POSITIVE_INFINITY.
    
    Since:
    
    0.8-riddler
    
    See Also:
    
    Double.POSITIVE_INFINITY, Double.NEGATIVE_INFINITY
  - IS_NAN
```
public static final Function IS_NAN
```
    Tells if a number is Double.NaN.
    
    Since:
    
    0.8-riddler
    
    See Also:
    
    Double.isNaN(double)
  - MIN
```
public static final Function MIN
```
    Returns the smallest (closest to negative infinity) of two numbers.
    
    Since:
    
    0.8-riddler
    
    See Also:
    
    Math.min(double, double)
  - MAX
```
public static final Function MAX
```
    Returns the largest (closest to positive infinity) of two numbers.
    
    Since:
    
    0.8-riddler
    
    See Also:
    
    Math.max(double, double)
  - GCD
```
public static final Function GCD
```
    Returns the Greatest Common Denominator of two numbers.
    The numbers WILL be rounded using Math.round(double) before the analysis.
    
    If the resulting value is out of the range of the long type, then an ArithmeticException is thrown.
    
    Since:
    
    0.8-riddler
    
    See Also:
    
    Functions.FLOOR, Functions.CEIL, ROUND, LCM
  - LCM
```
public static final Function LCM
```
    Returns the Least Common Multiple of two numbers.
    The numbers WILL be rounded using Math.round(double) before the analysis.
    
    If the resulting value is out of the range of the long type, then an ArithmeticException is thrown.
    
    Since:
    
    0.8-riddler
    
    See Also:
    
    Functions.FLOOR, Functions.CEIL, ROUND, GCD
  - ROUND
```
public static final Function ROUND
```
    Rounds to closest integer.
    
    Since:
    
    0.8-riddler
    
    See Also:
    
    Functions.FLOOR, Functions.CEIL, Math.round(double)
  - EQUALITY_THRESHOLD
```
public static final double EQUALITY_THRESHOLD
```
    This is the threshold used to consider values equal, that is, if two values a and b are separated by less than this threshold they will be considered to be equal, it has a default value of 1.0E-12

```
    Get the function for a given name.
    
    Parameters:
    
    name - the name of the function
    
    Returns:
    
    a Function instance
