RIGHTB function

The RIGHTB function in Jspreadsheet Formulas Pro is a useful tool that allows you to extract a specific number of bytes from the end of a given text string. For instance, if you have a lengthy piece of text and need to pull out the last few bytes, you can use this function. You simply specify the text string and the number of bytes you want to extract, and the function will return them. This is particularly useful for processing and analyzing data in Jspreadsheet.

Documentation

Returns a specified number of bytes from the end of a text string.

Syntax

RIGHTB(text, number_of_bytes)

Parameter	Description
`text`	The text string containing the bytes to return.
`number_of_bytes`	The number of bytes to return from the end of the text string.

Behavior

The RIGHTB function is used to extract a specific number of bytes from a text string, starting from the rightmost byte. This function is especially useful when dealing with languages that use double-byte characters. The behavior of RIGHTB across different types of inputs is as follows:

Text: RIGHTB works directly on text strings. It counts the number of bytes from the right of the text string as specified by the user and returns the corresponding characters.
Numbers: If a cell contains a number, RIGHTB treats it as a text string and operates accordingly.
Booleans: Boolean values (TRUE / FALSE) are treated as text strings ("TRUE" / "FALSE") by the RIGHTB function.
Empty cells: If the RIGHTB function is used on an empty cell, it returns an empty string.
Errors: If a cell contains an error, RIGHTB will return that error.

Common Errors

Error	Description
#VALUE!	This error is returned when the number of bytes to be returned is less than 0.
#REF!	This error is returned when the referred cell is invalid.

Best practices

Always ensure that the number of bytes to be returned is a non-negative number to avoid the #VALUE! error.

Be aware that RIGHTB counts bytes, not characters. Some characters may use more than one byte, especially in non-English languages.

Use the RIGHTB function in combination with other text functions for more complex text manipulation tasks.

If you are only dealing with single-byte characters, consider using the RIGHT function for simplicity.

Usage

A few examples using the RIGHTB function.

RIGHTB("Hello World", 5) returns "World"  
RIGHTB("Jspreadsheet Functions", 9) returns "Functions"
RIGHTB("12345", 2) returns "45"
