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 the CEILING() and ROUND() functions.SyntaxFLOOR(number)Parameter ValuesParameterDescription number Required. 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 ...
方法1、FLOOR 函数 在这介绍的函数,首先是 FLOOR 函数 MySQL 8.0参考手册函数说明: https://dev.mysql.com/doc/refman/8.0/en/mathematical-functions.html#function_floor 简单来说就是,返回x的最大整数值,那我们怎么用这个函数呢? 这个函数只能处理小数点部分,20001 也不是小数!不是小数我们可以把它变成小数,...
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...
