# 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)
