示例1: test_scalar

# 需要导入模块: from numpy import core [as 别名]
# 或者: from numpy.core import inf [as 别名]
def test_scalar(self):
        x = np.inf
        actual = np.isposinf(x)
        expected = np.True_
        assert_equal(actual, expected)
        assert_equal(type(actual), type(expected))

        x = -3.4
        actual = np.fix(x)
        expected = np.float64(-3.0)
        assert_equal(actual, expected)
        assert_equal(type(actual), type(expected))

        out = np.array(0.0)
        actual = np.fix(x, out=out)
        assert_(actual is out)
