pub fn round_half_even(value: f64) -> i64Expand description
Python’s round: halves go to the nearest even integer.
Ported rather than replaced by f64::round (which rounds halves
away from zero) so a stride lands on the same layers here as
upstream – a one-layer difference silently changes which experts a
deployment serves on which device.
Public so ferrox-models’ DSV4 window tier sizes by the same rule:
two copies would be free to drift, and a half-page disagreement
between placement and sizing is a page of window the budget did not
buy.
