The BinaryToUpper function converts the characters in a binary string or a single byte to their uppercase form. It performs a case conversion based on the ASCII character set, mapping lowercase characters (a-z) to their corresponding uppercase counterparts (A-Z). This function is particularly useful when you need to transform text data to uppercase for consistency, comparison, or formatting purposes. It supports both binary strings and individual bytes as input.


<binary/byte> The binary string or single byte to convert to uppercase.

Return Value

Success: Returns converted binary string or byte in uppercase.
Failure: Returns false.


The BinaryToUpper and BinaryToLower functions may seem unusual in the context of modern programming languages, as many high-level languages provide built-in string methods or functions for case conversion. However, in certain low-level or specialized scenarios, such as working with binary data or dealing with legacy systems, these functions can still be relevant and useful.

In some cases, binary data may contain character representations that need to be transformed to a specific case, regardless of the programming language or framework being used. The BinaryToUpper and BinaryToLower functions provide a straightforward way to perform case conversions for individual characters or binary strings, using the ASCII character set as a reference.

Additionally, these functions can be handy when working with specific protocols or file formats that require strict adherence to uppercase or lowercase conventions. By offering the ability to convert characters to the desired case, these functions allow for compatibility and consistency in data processing.




Example of usage:

my $a = bin("Hello");
say BinaryToUpper($a);
say BinaryToLower($a);
// hello
