I'm asking for help
For 3 weeks, I try to get along, but I don't succeed
I've created another scrip for data scans
one problem
reads healthy numbers well
negatives (65250 must -286)
I found a formula to calculate
unable to get stuck (65250 -65536 = - 286)
how to make correct numbers
positive and negative
