I'm not sure how to describe this properly, but llCos returns the result in radians instead of degrees and I need it in degrees. Here is an example to better explain it.

In Window's scientific calculator, I set the radio buttons to Dec and Degrees. I punch in 270 and hit cos. This gives me 0. Great! Now, I set the radio buttons to Dec and Radians. I punch in 270 and hit cos. Now it gives me .98438. This is exactly what SL is giving me. What is this garbage and how do I convert it to what I need? Thank you for any help.

Example script: llOwnerSay("llCos(270) is: " + (string)llCos(270));

Edit: Yes, I have tried *RAD_TO_DEG and that just makes the number even more useless. I may be using it improperly though.

Example script: llOwnerSay("llCos(270) is: " + (string)(llCos(270)*RAD_TO_DEG));

use the build in conversion constant'

you must convert the argument to radians as well: llCos(DEG_TO_RAD*270)

llCos takes it's argument in radians, not degrees. Your example has 270 , it needs to be 270 * DEG_TO_RAD .

Awesome! Thank you so much. I'll have to pay better attention to the function's arguments next time.
