Use the math.Trunc function to truncate a floating point number into its integer part and return the truncated floating point number.
Article Introduction:Use the math.Trunc function to truncate a floating-point number into its integer part and return the truncated floating-point number. Floating-point number is a data type used in computers to represent real numbers (including integers and decimals). However, in practical applications, sometimes we only care about the integer part of the floating point number, and hope to truncate the floating point number and get an integer result. At this time, we can use the Trunc function in the math package to achieve this. The trunc function is a function in the math package of the Go language (Golang) standard library.

How to call a function with a section appended to parameters in JavaScript?
Article Introduction:In JavaScript, you can call a function by passing parameters to it. However, sometimes it is necessary to call a function with some parameters already populated. This can be done using a technique called partial function application. What is a partial function application? Partial function application is a way of creating a new function by "pre-populating" some parameters of an existing function. This is useful when you want to create a new function that is similar to an existing function but has some parameters set. For example, suppose you have a function that calculates the area of a rectangle. The function takes two parameters - the width and height of the rectangle. Now imagine you want to create a new function to calculate the area of a square. This new function will be similar to the existing function, but it will only require one parameter - the sides of the square. This is part of the function application

From Novice to Master: Advanced Guide to Improving PHP Function Performance
Article Introduction:Proficient in PHP function performance optimization, from novice to expert: avoid dynamic function calls and call functions directly. Use namespaces to reduce function name resolution overhead. Avoid using local variables and use global variables whenever possible. Use immutable data types to avoid creating new copies. Cache function results to avoid double calculations. Use Opcache to cache compiled code to improve execution speed. Use the JIT compiler to compile PHP code into machine code to further improve performance.
