s/round/rint/ in exponential_biased
`rint` differs from `round` in that it uses the current FPU rounding
mode. It’s thus potentially faster, since it doesn’t have to save and
restore FPU state. It also is more reflective of developer intent –
most developers expect all FPU operations to use the current rounding
mode, and having exponential_biased follow that rule seems ideal.
