roundedDivideQ16()

i64 fl::anonymous_namespace{device_solve.cpp.hpp}::roundedDivideQ16	(	i64	numerator,
		i64	denominator )

Nearest integer of numerator / denominator, halves away from zero.

Truncating would bias every column toward zero and the bias does not cancel: the inverse is built from products of these.
