Fast Fixed Point Math for Java Financial Applications

 3r33625. 3r3-31. 3r3611. It is no secret that financial information (invoices, transactions, and other bookkeeping) is not very friendly with floating point numbers, and many articles recommend using a fixed point (fixed point arithmetic). In Java, this format is represented, in fact, only by the BigDecimal class, which cannot always be used for performance reasons. You have to look for alternatives. This article describes a self-written Java library for performing arithmetic operations on fixed-precision numbers. The library was created to work in high-performance financial applications and allows ...

3r3633. Most recently, I, like many users, was puzzled by the inability to change the address of this sensor. Google, of course, issued a bunch of articles about all sorts of multiplexers ...
