- jax.numpy.float_power(x1, x2)#
First array elements raised to powers from second array, element-wise.
LAX-backend implementation of
Original docstring below.
Raise each base in x1 to the positionally-corresponding power in x2. x1 and x2 must be broadcastable to the same shape. This differs from the power function in that integers, float16, and float32 are promoted to floats with a minimum precision of float64 so that the result is always inexact. The intent is that the function will return a usable result for negative powers and seldom overflow for positive powers.
Negative values raised to a non-integral value will return
nan. To get complex results, cast the input to complex, or specify the
complex(see the example below).
New in version 1.12.0.
x1 (array_like) – The bases.
x2 (array_like) – The exponents. If
x1.shape != x2.shape, they must be broadcastable to a common shape (which becomes the shape of the output).
y – The bases in x1 raised to the exponents in x2. This is a scalar if both x1 and x2 are scalars.
