在Transact-SQL 语句中,小数数值的常量自动转换为 decimal 数据类型,在转换时,使用最小的精度和小数位数。例如,常量 12.345 被转换为numeric值,其精度为 5,小数位为 3。 In Transact-SQL statements, a constant with a decimal point is automatically converted into anumeric data value, using the minimum prec...

2,在SQL Server中,小数常量的默认数据类型是decimal,decimal的优先级比float高。 In Transact-SQL statements, a constant with a decimal point is automatically converted into anumeric data value, using the minimum precision and scale necessary. For example, the constant 12.345 is converted into anumeric ...
Bei der Konvertierung einer Zahl in einen Wert des Typs decimal oder numeric mit einer geringeren Genauigkeit und einer geringeren Anzahl von Dezimalstellen wird der Wert standardmäßig von SQL Server gerundet. Wenn die SET ARITHABORT Option dagegen lautet ON, löst SQL Server beim ...
value of the specified <precision>. 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 这段描述比较清楚了,小数类型的定义格式为(P,S),即固定精度和小数位数;numeric 要求固定精度和小数位一样精确,小数位固定长度;而 decimal 不一定,可能会大于或等于固定精度P的长度,即小数位的长度在存储的时候比实际的长...

For FLOAT, the SQL standard permits an optional specification of the precision (but not the range of the exponent) in bits following the keywordFLOAT in parentheses. MySQL also supports this optional precision specification, but the precision value is used only to determine storage size. A precisi...
In this scenario,the system automatically converts the value we entered with three decimal places (123.456) to two decimal places (123.46). So, this is how an overflow in decimal places is handled. On the other hand, let’s seehow the system handles values with more than 12 integers: ...
conversion offloatvalues todecimalornumericis restricted to values of precision 17 digits only. Anyfloatvalue less than5E-18(when set using either the scientific notation of5E-18or the decimal notation of0.000000000000000005) rounds down to0. This restriction doesn't appear in SQL Server 2016 (13...
