This article examines the precision loss problem that occurs when transferring Java long integer data to JavaScript, stemming from differences in numeric representation between the two languages. Java uses 64-bit signed integers (long), while JavaScript employs 64-bit double-precision floating-point numbers (IEEE 754 standard), with a mantissa of approximately 53 bits, making it incapable of precisely representing all Java long values. Through a concrete case study, the article demonstrates how numerical values may have their last digits replaced with zeros when received by JavaScript from a server returning Long types. It analyzes the root causes and proposes multiple solutions, including string transmission, BigInt type (ES2020+), third-party big number libraries, and custom serialization strategies. Additionally, the article discusses configuring Jackson serializers in the Spring framework to automatically convert Long types to strings, thereby avoiding precision loss. By comparing the pros and cons of different approaches, it provides guidance for developers to choose appropriate methods based on specific scenarios.
