What is REAL Data Type?
The REAL storage class is used for numeric data with a decimal component. REAL values are stored as 8-byte floating-point numbers according to the IEEE 754 standard which means that they can represent a wide range of values including both very small and very large numbers.
When using the REAL data type it is important to be aware of precision issues. Due to the nature of floating-point representation, some values may not be stored exactly as entered. This can lead to small rounding errors, especially when performing calculations involving REAL values.
REAL vs NUMERIC in SQLite
When working with SQLite, understanding the differences between data types is important for efficient database design and query performance. Two common data types often confused are REAL
and NUMERIC
. While both can store numeric values, they have distinct characteristics that impact how data is stored and processed. In this article, we will learn about what is REAL
and NUMERIC
along with the examples and also see the differences between them.
