Bisection search, or binary search for us developers, is a technique for finding the best value within a given range of values. Technically speaking, Wikipedia says the “bisection method in mathematics is a root-finding method that repeatedly bisects an interval and then selects a subinterval in which a root must lie for further processing.” This…

How to Round to Arbitrary Precision in any Programming Language
How to Round to Arbitrary Precision in any Programming Language: an AMultiply your rounding number by 10^y where y is the precision to round to. Call your language’s built-in round() method on this number. Divide the result by 10^y. Easy peasy. It also makes it easier to implement different rounding methods because you’re always dealing with the digit at the same location in the number.
