Functions 22-5
Next Level Of Priority:
Powers:
x^y: x raised to the power of y, 3^5 = 243
Next Level Of Priority:
Multiplication / Division:
x * y: x multiplied by y, 20 * 30 = 600
x / y: x divided by y, 20 / 30 = 0.666667
Next Level Of Priority:
Addition / Subtraction:
x + y: x added to y, 20 + 30 = 50
x - y: x subtract y, 20 - 30 = -10
Next Level Of Priority:
Low Level Logic:
x == y: Is x equal to y? (Notice double equal signs) 1 if true 0 if false
x!=y: x does 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,
(ana1>2.5)&(ana2>3.5) returns 1.0 if analog channel 1 is greater
than 2.5 AND analog channel 2 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 return 1.0, else return 0.0. For example,
