sin() and cos() that use degrees

Hi all,

I was wondering if anyone knew of versions of sin() and cos() that use degrees. RHIDE's sin() and cos() use radians. I know how to convert between radians and degrees, but it doesn't work.

When I display a bitmap at the equivalent of 90 degrees, it's slightly off, because (I assume) of inaccuracies in converting between radians and degrees. Or is it inaccuracies with floating point numbers? Either way, could someone point me to a degrees version if cos() and sin()? I already tried using google but didn't get too much information.
