Port recent possible regression fixes

[eileenmcnaughton]

ports #29654 and #29653

While not reported as regressions I think these are likely to be experienced as regressions in some use cases (ie the lines in question might have been problematic before but are more likely to be hit now)

These are also both very safe changes - one removes a line that sets an unused variable & the other applies the same rounding that we use elsewhere to the tokens
