Sample expresions that use operators

Example:	Expression:
x is greater than y	x > y
x is less than or equal to z	x <= z
x is greater than y and x is less than or equal to z	(x > y) && (x <= z)
x is greater than y or x is less than or equal to z	(x > y) || (x <= z)
x is equal to 3 or x is equal to 6.4	(x = =3) || (x = =6.4)
x is not more than ten percent greater than y	x <= y*1.1 !(x>y*1.1)
If x is greater than y, then value is 100, else value is 200.	x>y?100:200
If x is not greater than y, then check if y is greater than z. Otherwise, return false.	!(x>y)?y>z:false x>y?false:y>z x<=y?y>z:false
