Managing Tasks

x + y: x added to y, 20 + 30 = 50
x - y: x subtract y, 20 - 30 = -10
x == y: Is x equal to y (Notice double equal signs) 1 if true 0 if false
x!=y: Is x not equal y 1 if true 0 if false
x > y: Is x greater than y 1 if true 0 if false
x >= y: Is x greater than or equal to y 1 if true 0 if false
x < y: Is x less than y 1 if true 0 if false
x <= y: Is x less than or equal to y 1 if true 0 if false
x & y: Logical AND operation. If x does not equal 0.0 AND y does not equal 0.0 then
return 1.0, else return 0.0. For example, (A1>2.5)&(A2>3.5) returns 1.0 if Task A1 is
greater than 2.5 AND Task A2 is greater than 3.5, else it returns 0.0
x | y: Logical OR operation. If x does not equal 0.0 OR if y does not equal 0.0 then return 1.0,
else return 0.0. For example, (A1>2.5)|(A2>3.5) returns 1.0 if Task A1 is greater than 2.5
OR if Task A2 is greater than 3.5, else it returns 0.0
