So last time I did complex math was a while back, so this is based on Google, but it seems instead of expanding into `exp` you could use `sinh` and `cosh` that are both available in SPIR-V. So for sin you can do something like sin(a)cosh(b) + icos(a)sinh(b). Please verify but that would greatly simplify the code.
