Abstract

The embodiment of the invention provides an expression processing method and device, equipment and a computer-readable storage medium. The method includes: parsing an expression to obtain an expression object in the expression; obtaining types of expression objects; carrying out an inverse Polish rotation on the expression according to the types of the expression objects to generate an inverse Polish expression; and executing the inverse Polish expression to generate an execution result. By implementing the embodiment of the invention, a conversion manner of the expression can be optimized, the problem that function objects cannot be called after format conversion is solved, and expansibility and execution efficiency of the expression are improved.

Description

technical field [0001] The present invention relates to the field of computer data processing, in particular to an expression processing method, device, equipment and computer-readable storage medium. Background technique [0002] A computer program is a list of instructions describing the actions performed by a computer or processor-based device. When a computer program is loaded and executed on computer hardware, the computer will follow the instructions of the computer program to operate in a predetermined manner. A large number of expressions are used in computer programs. Expressions are sequences of operators and operands. For example, expressions can be "3+2". In the process of the computer executing the expression, the computer cannot recognize the expression written in natural language, so it is necessary to perform corresponding format conversion on the expression for the computer to read, but the format conversion of the expression in the prior art can only Conv...
