Float vs. Double in Java

Date: 2025-02-10

Java offers float and double for representing decimal numbers, differing primarily in precision and storage size. double provides higher precision but consumes more memory than float. The article highlights potential precision errors due to how floating-point numbers are stored in binary, leading to unexpected results when directly comparing them using ==. It recommends using a tolerance threshold for accurate comparisons and choosing between float and double based on the application's need for precision and memory efficiency.
