jax.lax.nextafter#
- jax.lax.nextafter(x1, x2)[source]#
Returns the next representable value after x1 in the direction of x2.
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
