## What is the data type for decimal?

The Decimal data type provides the largest number of significant digits for a number. It supports up to 29 significant digits and can represent values greater than 7.9228 x 10^28. It is particularly suitable for calculations, such as financial ones, that require a large number of digits but cannot tolerate rounding errors.

## How do I get rid of decimal 0 in SQL?

## What is the example of 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 can be 0 (no digits to the right of the decimal point). Note: Synonyms for the decimal data type are dec and numeric.

## How does the decimal data type work?

Unlike FLOAT, the DECIMAL data type has fixed decimal places. The precision defines the total number of decimal digits to store within the number. This includes digits to the left and right of the decimal. The scale defines the total number of decimal digits to the right of the decimal.

## What is double precision in SQL?

To define a column whose data type is DECIMAL, use the following syntax: P is the precision that represents the number of significant digits. The range of P is from 1 to 65. D is the scale that represents the number of digits after the decimal point. The range of D is 0 and 30.

## What is the default precision for decimals in Excel?

The default precision is 38. s is the scale, which is the number of decimal digits to store to the right of the decimal point. The scale has a range from 0 to p (precision). Scale can be specified only if precision is specified. By default, the scale is zero.

## How are trailing zeros preserved in a decimal?

Decimal contains a scale factor that influences how ToString() works, and this scale factor is set differently depending on how the Decimal is constructed. If you want to preserve trailing zeros, construct the Decimal in a way that gives you enough data regarding the precision of the input.
