The Weekender Bonus Puzzle

A man walks into a bar and orders a Jameson. The bartender says, "Sir, that’ll be six dollars." The man reaches into his pocket and realizes that he left his wallet at home and that he has not a penny on him. He explains the situation to the bartender. The bartender takes a napkin and writes the number 228 on it, followed by a space, and then the number 456. He says, "If you can write a mathematical symbol in the space between those two numbers that results in a number that is greater than the first number but less than the second number, you can have the drink for free." The man thinks for a second and puts a symbol between the two numbers. The bartender looks and it and says, "Sir, enjoy your drink." What symbol did the man put between the two numbers?
