The SQL Floor function function returns the largest integer that is smaller or equal to the input expression.
The SQL FLOOR() function rounded up any positive or negative decimal value down to the next least integer value. SQL DISTINCT along with the SQL FLOOR() function is used to retrieve only unique value after rounded down to the next least integer value depending on the column specified. Syntax...
FLOOR ( numeric_expression ): This funcion returns the largest integer less than or equal to the specified numeric expression. ROUND ( numeric_expression , length [ ,function ] ):This function returns a numeric value, rounded to the specified length or precision. 上述3个取整函数,是个通用函数,...
The FLOOR() function returns the largest integer value that is smaller than or equal to a number. Tip:Also look at theCEILING()andROUND()functions. Syntax FLOOR(number) Parameter Values ParameterDescription numberRequired. A numeric value
SQL內置Function--数学函数 数学函数 这些标量函数通常对作为参数提供的输入值执行计算,并返回一个数字值。 说明 算术函数(例如 ABS、CEILING、DEGREES、FLOOR、POWER、RADIANS 和 SIGN)返回与输入值相同数据类型的值。三角函数和其它函数(包括 EXP、LOG、LOG10、SQUARE 和 SQRT)将输入值投影到 float 并返回 float ...
All you have to do is replace the ceiling() function in the query with the floor() function. Implementation Limitations These are the limitations: The floor() function maps all integer values to xs:decimal. See Also ceiling Function (XQuery) round Function (XQuery) XQuery Functions against ...
floor()向下舍入为指定小数位数.如：floor(1.45,0)= 1;floor(1.55,0) = 1 ceiling()向上舍入为指定小数位数.如：ceiling(1.45,0) = 2;ceiling(1.55,0)=2 拓展回答：SQL Aggregate 函数，SQL Aggregate 函数计算从列中取得的值，返回一个单一的值。有用的 Aggregate 函数：AVG() - ...
截取TRUNC(value, [scale]) Trunc(123.33) = 123 Trunc(123.567, 2) = 123.56 求最大整数FLOOR(value) Floor(128.3)=128 Floor(129.8) = 129 除了不能截取小数部分外,Floor几乎等同于Trunc函数。 求最小整数CELL(value) Cell(128.3)=129 Cell(129.8) = 13020...
语法: SQRT(number) 用途: 该函数返回数值number的平方根,输入值必须大于等于0,否则返回错误. 4.3. 函數:CEIL 语法: CEIL(number) 用途: 该函数返回大于等于输入值的下一个整数. 4.4. 函數:FLOOR 语法: FLOOR(number) 用途: 该函数返回小于等于number的最大整数. ...
