For doing arithmetic, Bro supports
+
-
*
/
and
%
.
In general, binary operators evaluate their operands after converting them
to the higher type of the two and return a result of that type.
However, subtraction of two count values yields an int value.
Division is integral if its operands are count and/or int.
+
and -
can also be used as unary operators. If applied to a count type,
they yield an int type.
% computes a modulus, defined in the same way as in
the C language. It can only be applied to count or int
types, and yields count if both operands are count types,
otherwise int.
Binary + and -
have the lowest precedence, *, /, and % have equal
and next highest precedence. The unary
+ and - operators have the same precedence as the !
operator Logical Operators.
See , for a table of the precedence of all Bro
operators.
