( numeric_expression ) Arguments numeric_expression An expression of the exact numeric or approximate numeric data type categories, or types that is implicitly convertible to float (except for the bit data type).Return Value Returns the same type as numeric_expression except for the following expressions. Specified expression Return type tinyint, smallint int
real/float float
Nonnumeric types that can be implicitly converted to float float Example This example uses the CEILING (SQL Server Mobile) function to round off the unit price for products that are priced more than 100 dollars. Copy Code SELECT OrderID, UnitPrice, CEILING (UnitPrice) AS "CEILING" FROM "Order Details" WHERE UnitPrice > 100 ORDER BY UnitPrice
返回大于或等于所给数字表达式的最小整数。语法
CEILING ( numeric_expression ) 参数
numeric_expression是精确数字或近似数字数据类型类别的表达式(bit 数据类型除外)。返回类型
返回与 numeric_expression 相同的类型。示例
下面的示例显示使用 CEILING 函数的正数、负数和零值。 SELECT CEILING($123.45), CEILING($-123.45), CEILING($0.0)
GO下面是结果集:--------- --------- -------------------------
124.00 -123.00 0.00 (1 row(s) affected)
返回大于或等于所给数字表达式的最小整数。语法
