Python modf Examples

Example #1

File: test_clmath.py Project: abergeron/pyopencl

def test_modf(ctx_factory):
    context = ctx_factory()
    queue = cl.CommandQueue(context)

    for s in sizes:
        a = cl_array.arange(queue, s, dtype=np.float32) / 10
        fracpart, intpart = clmath.modf(a)

        a = a.get()
        intpart = intpart.get()
        fracpart = fracpart.get()

        for i in range(s):
            fracpart_true, intpart_true = math.modf(a[i])

            assert intpart_true == intpart[i]
            assert abs(fracpart_true - fracpart[i]) < 1e-4
