Description
Technical Field
The present invention relates to the field of data processing technologies, and in particular, to a floating-point number calculation precision processing method, system, medium, and device. In particular to a processing method for JS floating point number calculation precision based on a babel compiler.
Background
At present, more and more applications are developed based on a JavaScript technology stack, financial type applications often involve more money calculation containing decimal places at the front end, and because the number type in the JavaScript is realized based on a double-precision floating point type of IEEE 754 standard, the precision of the double-precision floating point type number is lost during operation. Therefore, the processing of computational accuracy is a loop that has to be considered in terms involving JavaScript floating point number computations.
Common processing strategies are as follows: 1. the method is characterized in that adding, subtracting, multiplying and dividing tool functions which are specially used for processing the four fundamental operation precisions of the floating point number are packaged in advance, and the principle of processing the operation precisions in the adding, subtracting, multiplying and dividing tool functions is as follows: in the effective range of the integer supported by JavaScript, the operation precision of the integer does not have a problem, so the decimal is expanded by corresponding multiple of 10, the decimal is converted into the integer for operation, and the integer operation result is converted back to the numerical value containing decimal places. 2. Locations in code that involve floating point operations are computed using tool functions instead of JavaScript native code.
By writing the following shapes: add (0.1, 0.2) type patch code, instead of written directly as: 0.1+ 0.2.
However, this solution is inefficient, error prone and imposes a certain mental burden on the developer. And when the complex floating point number mixed four-arithmetic operation code needs to be written, the problems of excessively deep nesting of function calling and complicated coding exist, and the calculation result is very easy to be abnormal due to human negligence or carelessness.
