add long double precision support #4580

Open ZeunO8 opened 7 months ago

ZeunO8 commented 7 months ago

Adds support for long double. Everything seems to work fine and we get the added benefit of long double precision, allowing for larger masses and more refined precision.

The serialization and various parameters may need to be revisited as I haven't tested that.

Wow, quite some work went into this. What kind of application requires this long double precision?

Btw, support of long double seems compiler specific, msvc vs gcc and clang.

Use case lies within simulating masses of universal scale
