Dear all, In a cam profile generation program, I perform some boolean operations with angular values (input in degrees). I noticed some boolean operations fail due to a varying accuracy. The file in attachment will clarify what I mean. How can I make these values equal? Reduce the amount of significant numbers? Thanks in advance for any feedback! Kind regards, Jan  Accuracy.sm (8kb) downloaded 15 time(s).
