    # Float
    data = np.random.normal(size=300**2)
    data[np.random.randint(300**2, size=100)] = np.nan
    data = (data - np.nanmin(data)).reshape((300, 300))
    mask = np.isnan(data)
    eq = tf.eq_hist(data, mask)
    check_eq_hist_cdf_slope(eq)
    assert (np.isnan(eq) == mask).all()
    # Integer
    data = np.random.normal(scale=100, size=(300, 300)).astype('i8')
    data = data - data.min()
    eq = tf.eq_hist(data)
    check_eq_hist_cdf_slope(eq)
