# How To Get Numeric Value From Unicode Value Golang

Go Programming

Hey there, fellow Go developers! Today, I want to dive into a topic that I find incredibly interesting and useful: converting Unicode values into their corresponding numeric values in Golang. As a programmer, I often encounter scenarios where I need to work with Unicode characters and understanding how to convert them to numeric values has been a game-changer for me. So, let’s get into the nitty-gritty details of how to achieve this in Golang.

## Understanding Unicode and Numeric Values

Before we delve into the process of converting Unicode values to numeric values, let’s take a moment to understand what Unicode and numeric values are. Unicode is a standard for consistent encoding, representation, and handling of text expressed in most of the world’s writing systems. Each character in Unicode is assigned a unique numeric value known as a code point. These code points are typically written in hexadecimal form, often prefixed with `U+`. For instance, the code point for the Latin capital letter A is `U+0041`.

## Converting Unicode to Numeric Values in Golang

Now, let’s see how we can perform this conversion in Golang. Golang provides a convenient way to convert a Unicode value to its numeric representation using the `strconv` package. We can achieve this by utilizing the `ParseUint` function which takes the string representation of the Unicode value, the base (which is typically 16 for hexadecimal), and the bit size (which is 32 for Unicode code points).

“`go
package main

import (
“fmt”
“strconv”
)

func main() {
unicodeValue := “0041”
numericValue, err := strconv.ParseUint(unicodeValue, 16, 32)
if err != nil {
fmt.Println(“Error:”, err)
return
}
fmt.Println(“Numeric Value:”, numericValue)
}
“`

In the example code above, we take the Unicode value `0041` and use `strconv.ParseUint` to convert it to its corresponding numeric value. The resultant numeric value will be 65, which is the decimal representation of the hexadecimal Unicode value `0041`.

## Putting it to Use

Understanding how to obtain the numeric value from a Unicode value opens up a plethora of possibilities. Whether you’re working on parsing textual data, implementing internationalization features, or performing text processing, having this knowledge in your toolkit can be immensely beneficial.

## Conclusion

In conclusion, being able to convert Unicode values to their numeric counterparts in Golang is a valuable skill for any developer working with text data. By leveraging the `strconv` package, we can seamlessly perform this conversion and empower ourselves to tackle a wide range of text-related challenges. So, the next time you encounter a Unicode value, remember that unlocking its numeric representation is just a few lines of code away!
