jax.numpy.spacing#

jax.numpy.spacing(x,/)[source]#

Return the spacing betweenx and the next adjacent number.

JAX implementation ofnumpy.spacing().

Parameters:

x (ArrayLike) – real-valued array. Integer or boolean types will be cast to float.

Returns:

Array of same shape asx containing spacing between each entry ofx and its closest adjacent value.

Return type:

Array

Examples

>>>x=jnp.array([0.0,0.25,0.5,0.75,1.0],dtype='float32')>>>jnp.spacing(x)Array([1.4012985e-45, 2.9802322e-08, 5.9604645e-08, 5.9604645e-08,      1.1920929e-07], dtype=float32)

Forx=1, the spacing is equal to theeps value given byjax.numpy.finfo:

>>>x=jnp.float32(1)>>>jnp.spacing(x)==jnp.finfo(x.dtype).epsArray(True, dtype=bool)
