Function to find is a number is Odd or Even in AS3

i'm trying to create this function but i have this error:

1071: Syntax error: expected a definition keyword (such as function) after attribute returns, not false.
1084: Syntax error: expecting rightbrace before semicolon.



Thank You

function isOdd(number:int):Boolean; 
{
	//check if the number is odd or even
	if (number % 2 == 0)
	{
		returns false;
	}
	else
	{
		returns true;
	}
}
