Comparison

From the syllabus

AQA: Be familiar with and be able to use ... (3.1.1.4/4.1.1.4)}

• equal to, not equal to, less than, greater than, less than or equal to, greater than or equal to

Comparison operators are used to compare two or more values/variables returning either true or false (boolean values). They work as you would expect from Maths, in the table below we'll assume a = 4 and b = 5:

Operator	Description	Example
>	greater than	a > b -> False
<	less than	a < b -> True
>=	greater than, or equal to	a >= b -> False
<=	less than, or equal to	a <= b -> True
==	equal to	a == b -> False
!=	not equal to	a != b -> True

Be careful with == and do not confuse it with the assignment operator =.
