Add format string handling operator to the setexpr command. It allows to use C or Bash like format string expressions to be evaluated with the result being stored inside the environment variable name. setexpr <name> fmt <format> [value]... The following example setexpr foo fmt "%d, 0x%x" 0x100 ff will result in $foo being set to "256, 0xff".
