Java Double vs. BigDecimal

Date: 2024-02-12

Java's double and BigDecimal offer different approaches to floating-point numbers. double is a primitive type offering speed but sacrificing some precision due to its binary representation. BigDecimal, from the java.math package, provides arbitrary-precision decimal arithmetic, ensuring accuracy but at the cost of performance. The choice depends on application needs: prioritize double for performance-critical applications where minor precision loss is acceptable, and BigDecimal for financial or other scenarios requiring exact decimal calculations.
