jax.numpy.nextafter#
- jax.numpy.nextafter(x1, x2, /)#
Return the next floating-point value after x1 towards x2, element-wise.
LAX-backend implementation of
numpy.nextafter()
.Note that in some environments flush-denormal-to-zero semantics is used. This means that, around zero, this function returns strictly non-zero values which appear as zero in any operations. Consider this example:
>>> jnp.nextafter(0, 1) # denormal numbers are representable Array(1.e-45, dtype=float32, weak_type=True) >>> jnp.nextafter(0, 1) * 1 # but are flushed to zero Array(0., dtype=float32, weak_type=True)
For the smallest usable (i.e. normal) float, use

.Original docstring below.
- Parameters:
x1 (array_like) – Values to find the next representable value of.
x2 (array_like) – The direction where to look for the next representable value of x1. If
x1.shape != x2.shape
, they must be broadcastable to a common shape (which becomes the shape of the output).
- Returns:
out – The next representable values of x1 in the direction of x2. This is a scalar if both x1 and x2 are scalars.
- Return type:
ndarray or scalar
