## com.hp.hpl.jena.reasoner.rulesys.builtins
Class Quotient

    java.lang.Object
      com.hp.hpl.jena.reasoner.rulesys.builtins.BaseBuiltin
          com.hp.hpl.jena.reasoner.rulesys.builtins.Quotient

All Implemented Interfaces:
  Builtin

    public class Quotient

extends BaseBuiltin

Bind the third arg to the ratio of the first two args. If the arguments are integers then the result will be truncated to an integer.

Constructor Summary
`Quotient()`

Method Summary
`boolean` | `bodyCall(Node[] args, int length, RuleContext context)` This method is invoked when the builtin is called in a rule body.
`int` | `getArgLength()` Return the expected number of arguments for this functor or 0 if the number is flexible.
`java.lang.String` | `getName()` Return a name for this builtin, normally this will be the name of the functor that will be used to invoke it.

Constructor Detail

### Quotient

    public Quotient()

Method Detail

### getName

    public java.lang.String getName()

  Return a name for this builtin, normally this will be the name of the functor that will be used to invoke it.

### getArgLength

    public int getArgLength()

  Return the expected number of arguments for this functor or 0 if the number is flexible.

  Specified by:
    `getArgLength` in interface `Builtin`
  Overrides:
    `getArgLength` in class `BaseBuiltin`

### bodyCall

    public boolean bodyCall(Node[] args,
                            int length,
                            RuleContext context)

  This method is invoked when the builtin is called in a rule body.

  Specified by:
    `bodyCall` in interface `Builtin`
  Overrides:
    `bodyCall` in class `BaseBuiltin`
  Parameters:
    `args` - the array of argument values for the builtin, this is an array of Nodes, some of which may be Node_RuleVariables.
    `length` - the length of the argument list, may be less than the length of the args array for some rule engines
    `context` - an execution context giving access to other relevant data
  Returns:
    return true if the buildin predicate is deemed to have succeeded in the current environment
