Syntax  mod  Description  The mod (modulo) operator produces the modulo of one number with another. In other words, the result is always a number between 0 and the second operand. If both operands are positive, the result is identical to the remainder operator. For example, 7mod 2 produces 1 and 12 mod 5 produces 3.  Example  In this example, hours is the current time. It is moved back and forth by a random amount, but the final result must always be between 1 and 12 (the mod operation produces a number between 0 and 11 and then 0 becomes 12). var hours : int := 12
var hoursPassed : int
put "The time is now ", hours, " o'clock"
loop
randint (hoursPassed, 12, 12)
exit when hoursPassed = 0
if hoursPassed < 0 then
put hoursPassed, " hours before " ..
else
put hoursPassed, " hours later " ..
end if
put hours, " o'clock" ..
hours := (hours + hoursPassed) mod 12
if hours = 0 then
hours = 12
end if
put " it was ", hours, " o'clock"
end loop  Details  If the second operand is positive, then the result is always nonnegative. Likewise, if the second operand is negative, then the result is always nonpositive. If both operands are negative, the result is the same as the remainder operator.  See also  infix operators, precedence of operators and the rem and div operators.
