As with any mathematical or signal processing problem, the intended value range and accuracy should be known to decide about a suitable number format. Fixed point ("integer") or floating point (either using IEEE standard or a user specific format) are possible as well.

Personaly I would try a CORDIC implementation, as suggested.
