floating point numbers
1. What are floating point numbers
In the process of computer system development, several methods have been proposed to express real numbers. Typically, for
In the Java language, we can use the two basic data types of float and double to represent specific data.These two data types are essentially floating-point numbers (floating-point number), which is a numerical representation of the approximate
The IEEE binary floating-point Number Arithmetic standard (IEEE 754) is the most widely used standard for floating-point operators since the 1980s, and is used by many CPUs and floating-point operators. IEEE 754 provides four ways to represent
This article is based on Zhou Zhiming's "in-depth understanding of Java virtual machines"The instructions for a Java virtual machine consist of a byte-length opcode that represents the meaning of a particular operation (Opcode) and 0 to several
