This comment appears wrong to me
c = (t - sum) - y           // (t - sum) cancels the high-order part of y; subtracting y recovers negative (low part of y)

Should read:

c = (t - sum) - y           // (t - sum) yields those digits of y that did not underflow; subtracting y recovers the negative of under-flowed digits of y. 98.97.141.231 (talk) 20:03, 8 October 2022 (UTC)
