Question:Converting floats to rationals - sometimes

Under certain special circumstances it seems that Maple is converting floats to rationals - I noticed this in Maple 2021 when a^0.5 evaluated to sqrt(a). Prior to Maple 2017, a^0.5, evaluates to a^0.5.

Can anyone think of a reason for this change?

I'm not quite sure why it bothers me, but it does

See the attached for Maple 2016 and Maple 2017.
