Ramifications of using double precision

[Cruz]

Hello!

I'm a total noob and I just started reading the documentation. My first question is, what are the ramifications of using double precision vs. single precision? What trade off do I have to consider?

Thanks

Double precision will degrade the performance: SIMD optimizations are disabled and floating point operations will be slower.

Double precision can improve the quality of the simulation.
