Yes.

If you're interested, Fiora has written about it here: https://www.alchemistowl.org/pocorgtfo/pocorgtfo06.pdf
In short, it mostly follows IEEE 754 but has some exceptions, meaning that Dolphin has to add some extra code on top of the native CPU's floating point support in order to be sync-compatible.
