HEX

Syntax

HEX(str)

Description

Converts the number or string str to a hexadecimal string, where each byte of each character in str is converted to two hexadecimal digits.

For a numeric parameter N, UNHEX(N) is not the inverse of HEX(N). In this case, you can use CONV(HEX(N),16,10) instead.

Examples
