This Oracle tutorial explains how to use the Oracle / PLSQL ROUND function (as it applies to numeric values) with syntax and examples. The Oracle / PLSQL ROUND function returns a number rounded to a certain number of decimal places.
5,prad(粘贴字符) prad 在列的右边粘贴字符 6,Trim():截取字符串两端特殊字符 Trim(‘s’ from ‘string’);可以指定从字符串两边要截取的特殊字符 2, 数字函数 Round:传回一个数值,该数值是按照指定的小数位数四舍五入运算的特殊字符 ROUND( number, decimal_places ) number : 需四舍五入处理的数值, ...
ROUND The ROUND function rounds off a numeric valuentomdecimal places. The first operand is the value Oracle FastFormula rounds off, the second the number of places Oracle FastFormula rounds off to. Examples: ROUND(2.3401, 2)returns 2.34 ...

round(n,[m])该函数用于执行四舍五入,如果省掉m,则四舍五入到整数,如果m是正数, 则四舍五入到小数点的m位后。如果m是负数,则四舍五入到小数点的m位前。 trunc(n,[m]) 该函数用于截取数字。若省掉m,就截去小数部分(等价于trunc(n,0)),如 果m是正数就截取到小数点的m位后,若m是负数,则截取到...
