Math problem (possible human error)
when RULE_INIT {
log local0. "Maths Test: 57 + 22: [expr {57 +22}]. 57 + 022: [expr {57 + 022}]"
}
Returns:
: Maths Test: 57 + 22: 79. 57 + 022: 75
Can anyone explain why this might be?

Actually, that's not an error. When you are attempting to add "022", the TCL interpreter is treating that number as octal. octal 022 is 18 and 57 + 18 equals 75. The manual page for expr explains the rules on interpretation of numbers and their formats
