@bonkmaykr There's the std::int32_t types if your target supports them or the alternative bit-fields if you need an odd ball 47 bit sized integer.

I wonder if I can just cheat my way into making Time Falcon use fixed point math by making everything an integer shifted upwards by 16-bits

That's all fixed point math is at the end of the day. You really only need a type to make working with normal numbers easier and to make printing to decimal look right.
