## How do you extract the decimal part of a number?

The **TRUNC function** simply truncates (i.e. removes) decimal values if they exist – it doesn’t do any rounding. The TRUNC function returns the integer portion of the number which is then subtracted from the original value. The result is the decimal portion of the number.

## How do you set decimal places in SQL?

Generally you can define the precision of a number in SQL by defining it with parameters. For most cases this will be NUMERIC(10,2) or Decimal(10,2) – will define a column as a Number with 10 total digits with a precision of 2 (decimal places). It can also be declared as DECIMAL(10, 2).

## How do you handle decimal value in SQL?

**The Basic syntax of Decimal data type in SQL Server**

- p stands for Precision, the total number of digits in the value, i.e. on both sides of the decimal point.
- s stands for Scale, number of digits after the decimal point.

## How do I get two decimal places in SQL?

Select Convert(Numeric(38, 2), Minutes**/60.0**) from …. MySQL: Select Convert(Minutes/60.0, Decimal(65, 2)) from …. The Cast function is a wrapper for the Convert function.

## How do I reduce decimal places in SQL?

The SQL AVG() function returns the average value with default decimal places. The **CAST()** is used to increase or decrease the decimal places of a value. The CAST() function is much better at preserving the decimal places when converting decimal and numeric data types.

## How do I compare two decimal values in SQL?

Hence, this is equivalent to: declare @num1 decimal(18, 0) = 1.98; **declare @num2 decimal(18, 0) = 2.2**; SQL Server then assigns the values by converting the constants to the appropriate value, and both are being set to “2.”. You need to explicitly set the precision/scale if you want those values to be stored exactly.

## How do I remove decimal places in SQL?

**SQL Query to Remove Decimal Values**

- Using ROUND() function: This function in SQL Server is used to round off a specified number to a specified decimal places.
- Using FLOOR() function: It returns the largest integer value that is less than or equal to a number.

## What is difference between numeric and decimal in SQL Server?

There is a small difference between NUMERIC(p,s) and DECIMAL(p,s) SQL numeric data type. NUMERIC determines the exact precision and scale. DECIMAL specifies only the exact scale; the precision is equal or greater than what is specified by the coder.

## What is a decimal data type?

The decimal data type is **an exact numeric data type defined by its precision (total number of digits) and scale** (number of digits to the right of the decimal point). For example: … The scale of a decimal value cannot exceed its precision. Scale can be 0 (no digits to the right of the decimal point).

## Is number in SQL Server?

As defined in the official Microsoft SQL Server documentation, the ISNUMERIC function determines whether an expression is a valid numeric type. … If the input expression is evaluated to a valid numeric data type, SQL Server ISNUMERIC returns 1; otherwise, it returns 0.
