How do I write generic numeric utilities?

Go (or Golang) is a statically typed, compiled programming language designed for simplicity and efficiency. In Go, writing generic numeric utilities can help developers manage numeric types in a flexible and reusable way. Using type parameters introduced in Go 1.18, developers can create functions that work with any numeric type.

Example of Generic Numeric Utility


        package main

        import (
            "fmt"
        )

        // Add function can take any numeric type
        func Add[T int | int32 | int64 | float32 | float64](a, b T) T {
            return a + b
        }

        func main() {
            fmt.Println(Add(5, 10))            // Output: 15
            fmt.Println(Add(5.5, 10.5))        // Output: 16
        }
