Floor(value)	Returns the largest integer that is not greater than value. Arguments A Single, Double, and Decimal. Return Value The type of value. Example SELECT VALUE product FROM AdventureWorksEntities.Products AS product WHERE FLOOR(product.ListPrice) == CEILING(product.ListPrice)
Power(value, exponent)	Returns the result of the specified value to the specified exponent. Arguments value: An Int32, Int64, Double, or Decimal. exponent: An Int64, Double, or Decimal. Return Value The type of value. Example Power(748.58,2)
