Returns val**factor of the given value, if defined.
cirq.pow(
val: Any, exponent: Any, default: Any = RaiseTypeErrorIfNotProvided
) -> Any
Values define an extrapolation by defining a pow(self, exponent) method.
Note that the method may return NotImplemented to indicate a particular
extrapolation can't be done.
Args |
|---|
val
|
The value or iterable of values to invert.
|
exponent
|
The extrapolation factor. For example, if this is 0.5 and val
is a gate then the caller is asking for a square root of the gate.
|
default
|
Determines the fallback behavior when val doesn't have
an extrapolation defined. If default is not set and that occurs,
a TypeError is raised instead.
|
Returns |
|---|
If val has a pow method that returns something besides
NotImplemented, that result is returned. Otherwise, if a default value
was specified, the default value is returned.
|
Raises |
|---|
TypeError
|
val doesn't have a pow method (or that method returned
NotImplemented) and no default value was specified.
