# times(?Factor1, ?Factor2, ?Product)

Succeeds if Product is the result of multiplying integer arguments Factor1 and Factor2.

Factor1
  An integer or a variable.
Factor2
  An integer or a variable.
Product
  An integer or a variable.

## Description

Defines the arithmetic relation Factor1 * Factor2 = Product. If all arguments are instantiated times/3 succeeds if this relation holds. If one of the arguments is uninstantiated, it is bound to an integer such that the relation holds. Note that this is not always possible. If the system is in coroutining mode and more than one argument is uninstantiated, times/3 delays until at least two of the arguments are known.

### Modes and Determinism

- times(+, +, -) is det
- times(+, -, +) is semidet
- times(-, +, +) is semidet

### Fail Conditions

Fails if it is impossible to find an integer instantiation such that Factor1 * Factor2 = Product holds

### Exceptions

(4) instantiation fault
  more than one argument is uninstantiated (non-coroutining mode only)
(5) type error
  an argument is neither an integer nor a variable

## Examples

    Success:
       times(2, 3, 6).
       times(2, 3, Z).                   % gives Z=6
       times(X, 3, 6).                   % gives X=2
       times(2, Y, 6).                   % gives Y=3

    Fail:
       times(3, 4, 5).
       times(3, X, 5).

    Error:
       times(2.0, 3.0, 6.0).             (error 5)
       times(1 + 4, 2, 10).              (error 5)
       times(X, 1, Z).                   (error 4)
