Introduction to the SQL ROUND function. The ROUND function is a math function that rounds a number to a specific length or precision. The following illustrates the syntax of the ROUND function. ROUND (numeric_expression,precision); The ROUND function accepts two arguments.

The SQL Server provides various SQL Mathematical Functions, which allows us to perform basic math functionality. For instance, you can use SQL Mathematical functions to find the elementary exponential value, square root, floor, round, logarithmic, and trigonometric functions. Transact-SQL derives all system date and time values from the operating system of the computer on which the instance of SQL Server runs. Higher-Precision System Date and Time Functions.
