Super interesting product I'll definitely be taking a deeper look at this when I'm at work tomorrow.

I notice all your comparisons are with floating point and integer types. I was recently looking at SIMD as a possible way to speed up some of our calculations. But we create financial software and most data is typically stored as decimals not floating points to avoid problems with binary floating point precision during calculations.

Does quest handle decimals, just without the SIMD speed up?

Is this just a dead end? Are there any SIMD implementations that deal with decimal numbers? I considered Hacky workarounds like using integer based types internally and then treating them as as fixed point decimals for display but that doesn't give enough range for my purposes.
