Performs math functions and stored the result in a variable. The math
follows a C-like precedence, as follows, with the top of the list having
the highest priority.
Operators Function
------------------------------------------------
! logical not
* integer multiply
/ integer divide
+ integer addition
- integer subtraction
> greater than (result is non-zero or zero)
>= greater than or equal (result is non-zero or zero)
< less than (result is non-zero or zero)
<= less than or equal (result is non-zero or zero)
= or == equals (result is non-zero or zero)
!= not equal (result is non-zero or zero)
& or && logical and (result is non-zero or zero)
| or || logical or (result is non-zero or zero)
True is any non-zero number, and False is zero. In the expression, you may
use T and F as true and false. Parentheses () have highest precedence,
so inside the parentheses is always evaluated first.
examples:
#math {heals} {$mana/40}
Assuming there is a variable $mana, divide its value by 40 and store the
result in $heals.
#action {^You receive %0 experience} {updatexp %0}
#alias updatexp {#math {xpneed} {$xpneed-%%0}
Let's say you have a variable which stores xp needed for your next
level. The above will modify that variable after every kill, showing
the amount still needed.
