Arithmetic operations

In this section, we embark on a focused exploration of one of the cornerstone aspects of bytecode: arithmetic operations. These operations are the mathematical underpinnings that breathe life into Java programs, shaping the numerical landscape of computations within the JVM.

Bytecode arithmetic operations follow a fundamental principle: they operate on the first two values on the operand stack, performing the specified operation and returning the result to the stack. This session delves into the intricacies of bytecode arithmetic, shedding light on its nuances, behavior, and impact on program execution.

The arithmetic operations in bytecode are subdivided into two major categories: those involving floating point numbers and those dealing with integers. Each category exhibits distinct behaviors, and understanding these differences is crucial for Java developers seeking precision and reliability in their numerical computations.

As we navigate the bytecode...
