For an argument why S.Zero.evalf() should return a Float, see issue 3587.
And that's probably not the only place that it is assumed that evalf()
returns a

But that gores back to why Float(0) gives 0. Otherwise 1.0*x - 1.0*x would
not give 0, whereas core code expects it to.

This should probably give 0.0

These (related examples) should also probably give 0.0
Float(1.0) * Float('0.0')
0
Integer(1) * Float('0.0')
0
