conditionA is greater than or equal to
conditionB.
<
(less than) conditionA is less than conditionB.
(less than or

Logic (Boolean) Operators
Logic (Boolean) operators compare conditionA and
conditionB and return
1
if the conditional statement is true.
They return
0
if the conditional statement is false. conditionA
and conditionB can be real numbers, expressions, or lists.
If both conditions are lists, they must have the same number
of elements. If one condition is a list and the other a non-list,
the non-list is compared with each element of the list, and a
list is returned.
