Floating-point number processing method, apparatus and device, and computer readable storage medium

Abstract

The invention provides a floating-point number processing method, apparatus and device, and a computer readable storage medium. The floating-point number processing method comprises the following steps: assigning binary data of a floating-point number to an integer type member variable of a common variable; due to the fact that a plurality of member variables in the common variables share the memory address space, after the binary data of the floating-point number is assigned to the integer type member variables of the common variables, storing the binary data of the floating-point number in the memory address space pointed by the floating-point type member variables of the common variables; and obtaining decimal data of the floating-point number by printing the floating-point type membervariable of the community variable. The technicians do not need to express formats according to a binary scientific counting method of floating-point numbers specified by the IEEE754 standard. The complex process of analyzing the binary data of the floating-point number into the corresponding decimal data is achieved through manual calculation or programming, and the accuracy and efficiency of obtaining the decimal data corresponding to the binary data of the floating-point number are improved.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a floating-point number processing method, device, equipment and computer-readable storage medium. Background technique [0002] At present, on microprocessors with different architectures, all types of data are stored in binary data in memory and registers, that is, they are all represented as a sequence of 0 and 1. According to different data types, the computer adopts the analysis method corresponding to the data type to analyze the binary data to obtain the corresponding decimal representation. [0003] The IEEE Binary Floating-Point Arithmetic Standard (Institute of Electrical and Electronics Engineers 754, referred to as the IEEE754 standard) stipulates that for a single-precision floating-point number, the memory corresponding to the single-precision floating-point number is divided into a sign bit, an exponent field, and a mantissa field to store binary numbers....

AI Technical Summary

Problems solved by technology

[0006] The present invention provides a floating-point number processing method, device, equipment, and computer-readable storage medium, which are used to solve the problem of obtaining floating-point decimal data in the prior art. It needs to be manually or programmed by technicians, starting from the binary format of floating-point numbers. Extract the values ​​of the sign bit, exponent field, and mantissa field from the data, and then complete the above-mentioned complex calculation process, which is very error-prone, takes a long time, and is very inefficient.
