jax.numpy.ldexp(x1, x2, /)[source]#

Returns x1 * 2**x2, element-wise.

LAX-backend implementation of numpy.ldexp().

Original docstring below.

The mantissas x1 and twos exponents x2 are used to construct floating point numbers x1 * 2**x2.

  • x1 (array_like) – Array of multipliers.

  • x2 (array_like, int) – Array of twos exponents. If x1.shape != x2.shape, they must be broadcastable to a common shape (which becomes the shape of the output).


y – The result of x1 * 2**x2. This is a scalar if both x1 and x2 are scalars.

Return type:

ndarray or scalar
