Description
https://github.com/pydata/xarray/discussions/5865#discussioncomment-1636647
I wonder if it's possible to implement a built-in function like:
da.str.format("%.2f") or xr.string_format(da, "%.2f)
To wrap:
import xarray as xr
da = xr.DataArray([5., 6., 7.])
das = xr.DataArray("%.2f")
das.str % da
<xarray.DataArray (dim_0: 3)>
array(['5.00', '6.00', '7.00'], dtype='<U4')
Dimensions without coordinates: dim_0

Research direction
Start with the linked discussion and the proposed DataArray string-formatting examples. Compare the suggested da.str.format and xr.string_format APIs, then determine the intended behavior and scope before identifying the relevant xarray implementation and tests; done means a supported formatting API with coverage for the shown example.
