Double precision math operations.

BGADII

When I try to use double, a lot of the functions like sq() don't accept doubles. Is there somewhere I can find equivalent functions for doubles?

Also, why don't PVectors accept doubles? Methods like pvector.mult(double) don't work. Any way around this?

Yes, I feel your pain. This is something I wish would be changed in a future Processing - no real benefit to it.

So, you can use Math.* functions.

Also feel free to steal this (back) - https://github.com/praxis-live/praxis/blob/master/praxis.code/src/net/neilcsmith/praxis/code/userapi/PVector.java - refactored PVector to use double which I use in Praxis LIVE - I rewrote the whole Processing API to be based around double instead! :-)

Also, don't forget to suffix all fractional literals w/ d. Like this: 2.7d, -.5d, 1e3d. L-)

B/c for ".pde" files Processing's pre-processor automatically suffixes all fractional literals w/ f if there's none already. :-\"

Wow, no idea about that. Thanks for the heads up.

This is perfect. I need to take a look at Praxis live again. By the way, how do I incorporate it back into Processing as a library? First time doing something like this manually.
