It has occoured to me that i compare a lot of numbers that i want to be roughly the same like 103 and 105 = good or 3.2 and 3.1 = good and writing out the "If a+3 > b and a-3<b then" to give it a range is tedious, harder to read and i imagine not as good performance as possible alternatives so i was wondering if there is any kind of operator or .net function to get a true or false from 2 numbers where i can define the accuracy they must meet at?
