Using latest xarray and numpy >= 1.24.0, the following code generates a warning. This function is called when saving datasets to disk using dataset.to_netcdf:

python import numpy as np from xarray.coding.times import cast_to_int_if_safe array = np.array([1., 2., np.nan]) cast_to_int_if_safe(array)

$HOME/projects/xarray/xarray/coding/times.py:619: RuntimeWarning: invalid value encountered in cast int_num = np.asarray(num, dtype=np.int64) array([ 1., 2., nan])
