Zero is zero, but signs are a direction. There are multiple parts to numbers. Stand in place and turn around: how far did you go from where you started? Nonet

Zero is zero, but signs are a direction. There are multiple parts to numbers.
Stand in place and turn around: how far did you go from where you started?
Nonetheless, I agree. It's a bad idea.
- quietbritishjim 3y agoBy that logic there should be e.g. +4.0 and +4.0- (for when you go 4m forwards vs when you go 4m forwards but also turn around at the end).
- andrewmcwatters 3y agoIn vector maths, this would just be +4.0.
- Dylan16807 3y agoAnd the same is true of zero. Especially when you consider a two-dimensional vector. How would you encode/interpret facing in a complex zero?
