The {{KW|HEX$}} function returns the base 16 hexadecimal representation of an [[INTEGER]], [[LONG]] or [[_INTEGER64]] value as a [[STRING]].

{{PageSyntax}}

:''result$'' = {{KW|HEX$}}({{Parameter|decimal_number%}})

{{PageDescription}}
|
|
* The function returns the string hexadecimal (base-16) representation of a ''decimal'' integer.
|
|
* If the parameter is not an Integer, it will be converted to one by HEX$.
|
|
* The function does not return a leading sign space so [[LTRIM$]] is not necessary.
|
|
* Can be used in place of [[STR$]] to trim both sides of positive decimal values 0 to 9 only.
|
|
* [[VAL]] can convert the string value back to a decimal value by prefixing the string return with "&H".
|

''Example:'' Comparing decimal, hexadecimal and octal string values 0 to 15.
