minus-squareMBM@lemmings.worldlinkfedilinkarrow-up3·1 年前Math.Sqrt((x-y) * (x-y)) (I’ve actually seen someone use this)
minus-squareArtyom@lemm.eelinkfedilinkarrow-up2·1 年前I’ve been staring at it for 10 minutes and I’m still not convinced it works.
minus-squareuberrice@feddit.delinkfedilinkarrow-up3·1 年前Simple, 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
