minus-square@[email protected]linkfedilink2•8 months agoI’ve been staring at it for 10 minutes and I’m still not convinced it works.
minus-square@[email protected]linkfedilink3•8 months agoSimple, really. Abs(x-y) is the difference between the two numbers, absolute, so positive value. So, adding abs(x-y) to the smaller of the two numbers turns it into the bigger number. Plus the bigger number, now you have 2 times the bigger number
