round static method

  1. @visibleForTesting
double round(
  1. double v
)

Rounds to 1 decimal place to reduce noise in coordinates.

Propagates NaN/Infinite as-is — _position detects them with .isFinite before including the coordinates in the result.

Implementation

@visibleForTesting
static double round(double v) {
  if (!v.isFinite) return v;
  return (v * 10).roundToDouble() / 10;
}
