Calculate element-wise base-2 exponential of input.
JAX implementation of numpy.exp2.
x (ArrayLike) – input array or scalar
An array containing the base-2 exponential of each element in x, promotes to inexact dtype.
Examples
jnp.exp2 follows the properties of the exponential such as \(2^{a+b} = 2^a * 2^b\).
>>> x1 = jnp.array([2, -4, 3, -1]) >>> x2 = jnp.array([-1, 3, -2, 3]) >>> jnp.exp2(x1+x2) Array([2. , 0.5, 2. , 4. ], dtype=float32) >>> jnp.exp2(x1)*jnp.exp2(x2) Array([2. , 0.5, 2. , 4. ], dtype=float32)
