Element-wise round-to-nearest-even — returns a new tensor whose values are round(a) with the same shape and dtype as a.

Not differentiable: a is detached from the autograd graph.

Math

$y_i = \operatorname{round}(x_i)$ (round-half-to-even / banker's rounding).

Shape

Output shape equals input shape (elementwise).
