You cannot live with it in any system where agency can be taken because of how exploitable it is. If you set up a genetic algorithm in a life simulation and foolishly set it to use floating points "nature" will select for utilizing free energy as a matter of course.
HFT + floating point = economy crashed by duping inflation without real item duping
- bidirectional 6y agoHFT programs absolutely use floating point, you don't have time to waste using rationals/fixed point/whatever. I've no idea where this misapprehension has come from, in my experience the more complicated the work you do in finance, the more you balk at the idea of not using floating point.
- pgwhalen 6y agoAs some sibling comments suggest, not all finance is created the same. Trading systems often use floating point, but banking/accounting systems used fixed point. The key is whether your system needs to tally up your monies into a known quantity and ensure it is all accounted for. If you summed up the transactions across a number of customer accounts at a bank for instance, it's critical that they all net out.
