Question:hardware evaluation and integrals

I can write evalhf(sin(.25)) and get an answer with more precision than simply writing evalf(sin(x)). When I create a loop and time it I see that evalhf is much faster. Unfortunately, I can't seem to take advantage of this when doing numeric integration. e. g. evalhf(int(sin(x),x=0..4)) doesn't work. Some numeric integration problems are very slow and it would be nice to speed them up with hardware evaluation. Any way to do this? -thanks
