floating point numbers

weg

Hi all,

Using the BS2p, I need to take the sine and cosine of pretty precise numbers.· For example, I need to evaluate the sine(xx.xxxxx) to·4·or 5 decimal places.· I know the BS2p has no "formal" way of using floating point numbers nor do I want to purchase the 8-pin IC to work with floating point #s, so I was just wondering if someone knows of a solution to my problem (perhaps an include file or some sort of hack)?· Please don't make me resort·to a PIC (using PIC C).

Thanks in advance!

Or try this URL for CORDIC sine and cosine:

For 5 decimal places, that method would have to be extended to double precision, but the principle is the same.
