BASE function

BASE function:
This article describes the formula syntax and usage of the BASE function in Microsoft Excel.
 
Description
Converts a number into a text representation with the given radix (base).
 
Syntax
BASE(Number, Radix [Min_length])
 
The BASE function syntax has the following arguments.
Number    Required. The number that you want to convert. Must be an integer greater than or equal to 0 and less than 2^53.

Radix    Required. The base radix that you want to convert the number into. Must be an integer greater than or equal to 2 and less than or equal to 36 because Base function is a converter for binary, octal or hexadecimal numbering formats as well as it can convert the values up to the end of alphabetic.

Min_length    Optional. The minimum length of the returned string. Must be an integer greater than or equal to 0.
 
Remarks
If Number, Radix, or Min_length are outside the minimum or maximum constraints, BASE returns the #NUM! error value.
 
If Number is a non-numeric value, BASE returns the #VALUE! error value. Any non-integer number entered as an argument is truncated to an integer. The maximum value of the Min_length argument is 255.
