Calculate the base-2 exponential of each element in the input. That is, $\text{[math]}$ .

Parameter	Type	Description
x	array_like	Input array or scalar

Parameter	Type	Default Value	Description
out	ndarray or ndarray tuple	None	Location where the calculation result is stored. If provided, it must have a shape which the inputs broadcast to. If not provided, a freshly-allocated array is returned.
where	array_like	None	This condition is broadcast over the input. At locations where the condition is true, the out array stores the result. Elsewhere, the out array retains its original value.
**kwargs	-	-	Other keyword arguments. Refer to the NumPy official document Universal functions (ufunc).

Type	Description
ndarray/scalar	Element-wise base-2 exponential of x
