[Numpy-discussion] Downcasting to smallest storage

I am sorry if I have missed anything obvious here, but is there a fast
simple way to downcast an array to the smallest storage that hold
array data within a specified precision - e.g.
a = array([1.0])
small_a = fantasy_function(a, rtol=1.0000000000000001e-05, atol=1e-08 )
b = array([1.2])
small_b = fantasy_function(b, tol=1.0000000000000001e-05, atol=1e-08)
where a.dtype becomes, say, uint8, and b.dtype becomes float32?
Thanks a lot,
