Computational Performance in Fintech Applications
computation Many types of applications do not require high-performance computations because they simply perform very few or infrequent calculations. This also applies to many financial applications. However, there are financial applications, such as banking or insurance ones, that occasionally perform a significant number of computations. In this article, I will show an example of an application that calculates simulations of profits from investment funds, where the simulation time was reduced 100-fold (in words: a hundred times). The observations made are universal and can be applied in other cases as well. Calculation Accuracy As we know, calculation accuracy depends on the data type used. In Java, for example, we have types: float , double , which have limited precision int , long , which allow storing integers losslessly BigDecimal , which allows storing decimal numbers with any specified precision In most projects I have seen, financial calculation...
