I have a task to count some data sent by modbus protocol. Standard mathematical instruction block has only "+", "-", "*" and "/" operations but i need to count x=√(a²+b²) and see no chance to make square root operation. Thank You for Your help if anyone has an idea how to count it in Logo

I make a test with the UDF "Wurzel_opt_32767.lma". See attachment. Attachment Square_root_0BA8.Standard.zip (157 Downloads)
