![]() ![]() Any value other than 0, causes the function to truncate the result to the number of decimals. If 0 (or omitted), the function performs regular rounding, whereby a number of 5 or greater increases the next digit. operation: an optional parameter that affects rounding operations.decimals: the number of decimal places to round number to.number: a floating-point (decimal) number to be rounded.SQL Server's Round function goes one step further, by accepting up to three arguments: Rounding functions can vary quite a bit in their implementation some only round to an integer, while others let you specify the number of decimal places to round to. Here's a query against the ClassicModels Sample Database that shows the signed and unsigned (absolute) deviation of customers' credit limits, grouped by city: RoundĪnother extremely popular numeric function is Round. The latter is where the Abs function comes in. The deviation can either be signed or unsigned. In mathematics and statistics, deviation is a measure of difference between the value of a variable and some other value, often that variable's mean, or average. In simpler terms, Abs returns the positive version of a given number, whether its positive or negative to begin with. Hence, the Abs function accepts a numeric value as its argument and returns its absolute equivalent. These are not the Abs that people train to get ready for the beach. ![]() ![]() In today's installment, we'll be moving on to numerical functions, a category that is highly useful in the generation of statistics and calculated values! Abs In part 1 of this series, we explored string functions. Therefore, it's a good idea to brush up on the SQL Server specific implementations of common SQL function. While some functions are amazingly similar across the board, exact names and signatures may vary. Like most modern relational database offerings, SQL Server comes loaded with an impressive collection of built-in functions.
