lessthanorequalto

Less than or equal to is a mathematical symbol denoted by ≤. It is used to indicate that a value is either less than another value or exactly equal to it. For example, the statement "x ≤ 5" means that x can be any number that is smaller than 5 or is precisely 5. This symbol is fundamental in expressing inequalities and is widely used in algebra, calculus, and various branches of computer science and logic.

When comparing two quantities, say a and b, the expression a ≤ b asserts that the value of a is not greater than the value of b. This can be broken down into two possibilities: either a < b (a is strictly less than b) or a = b (a is equal to b). The symbol ≤ is a compound operator, combining the concepts of "less than" and "equal to." Its counterpart is the "greater than or equal to" symbol, ≥.

In programming languages, the less than or equal to operator is often represented by `<=`. It is commonly used in conditional statements to control program flow, such as in loops or decision-making structures. For instance, a loop might continue as long as a counter variable remains less than or equal to a specified limit. Understanding this symbol is crucial for interpreting mathematical expressions and logical conditions.
