Ethereum: Understand the decimal storage requirements in MS SQL
When it comes to storing data on a database, selecting the right type of storage is crucial. In this article, we will immerse ourselves in the decimal storage requirements of Ethereum, in particular in Microsoft SQL Server (MS SQL), and explore the GAAP standard quotes for money.
Decimal storage requirement: a brief overview
To understand the requirement of decimal storage of Ethereum in MS SQL, clarifions first what a decimal is. In mathematics, a decimal is a number represented as an infinite number of figures after the decimal point (for example, 0.5 or 3.14159). This means that when you store money, you need to represent it using fractions.
In MS SQL, the standard GAAP quotes decimal (13.4) for money. This format includes:
- A single character “m” representing a monetary unit
- Three figures after the decimal point (’13’) indicating the fractional part of the number
- Four figures after the decimal point (‘4’) to represent the thousandth place
This decimal format is widely used in financial applications and guarantees precision when it comes to large sums of money.
Why decimal (13.8) might not be preferred
Although CEO quotes (13.4) are commonly used for currency storage, some may say that the use of decimal (13.8) could be more intuitive or flexible. However, there is a valid reason to prefer the latter:
* Fractionary precision
: MS SQL provides fractional precision in its decimal data types, including decimal (18,2). This allows you to store and manipulate complex financial calculations with greater precision.
On the other hand, the CEO quotes (13.4) are limited to 12 digits or less after the decimal point, which can make it more difficult to represent certain financial concepts with precision.
Conclusion
In conclusion, when storing money in MS SQL for Ethereum, the use of GAAP standard quotes (13.4) is the recommended approach. This format ensures a precise representation of monetary values and provides a high degree of precision for complex calculations. Although the decimal (13,8) may seem more intuitive at first glance, it lacks fractional precision, which makes it less suitable for financial applications.
To give you a better idea, here is an example of how MS SQL would store the value 3.14159265358979323846 using the two formats:
Gaap quotes (13.4)
| Decimal value | Fractional representation |
| — | — |
| 3.14159265 … | 0.00000000 |
Decimal (18.2)
| Decimal value | Fractional representation |
| — | — |
| 3.14159265358979323846 … | 0.0000000000000000001 |
As you can see, the decimal representation is more precise and precise when using the fractional precision characteristics of MS SQL.
I hope this article has provided a complete understanding of decimal storage requirements in MS SQL for Ethereum. If you have any other questions or concerns, do not hesitate to ask!
