The action of dividing, rounding, then multiplying causes the result to be rounded to the nearest 5. So, this example would perform these steps: This function first doubles the number you wish to round, and then rounds it. To round to the nearest 5, you use the ROUND function and divide your number by 5, then multiply it by 5.įor example: SELECT ROUND(3162.845/5)*5 FROM dual To always round down, you would use the FLOOR function, which is the opposite of the CEILING function mentioned above. It could round up, depending on your input value. However, this will not always round down. You can use the ROUND function to round to 2 decimal places, by specifying the number 2 as the second parameter. How Can Oracle Round Down 2 Decimal Places? This function rounds a number up to the specified value, so you can use the CEILING function to round all of your values up.Ī detailed description and examples of this function is coming soon. If you want to always round up in Oracle, you would use the CEILING function. It doesn’t always round up, as you can see in the examples below. The Oracle ROUND function will round the number up or down, depending on the decimal places specified.

The value returned is always of data type DATE, even if you specify a different datetime data type.

If roundto is omitted, the input is rounded to the nearest day.

roundto can be any valid format mask (e.g.

input needs to be a date or datetime with timestamp.

If you are using the Oracle ROUND function with dates, then:

For BINARY_FLOAT and BINARY_DOUBLE input values, the value is rounded to the nearest even number.

For NUMBER input values, the value is rounded away from 0 (e.g.

If roundto is specified, the result is in a NUMBER data type.

If roundto is omitted, the result is in the same data type as the input value.

If roundto is 0 or omitted, the result is rounded to 0 decimal places.

If roundto is negative, the result is rounded to the left of the decimal point.

If roundto is positive, the result is rounded to the right of the decimal point.

input needs to be a numeric data type, or a value that can be converted to a numeric data type (such as a number inside a VARCHAR value).

If you are using the Oracle ROUND function with numbers, then: This function can be used with both dates and numbers. If it is a date, you specify the part of the date.

If it is a number, then you specify the decimal places here.

roundto (optional): This determines what the input value is rounded to.

It can be any numeric data type, or any date data type.

input (mandatory): This is the value that is rounded.

The parameters of the Oracle ROUND function are: Let’s take a look at what these values are used for. The syntax for the ROUND function is: ROUND( input, roundto) You can supply a date value to it, as well as the format, and it will round the date to that format.

ROUND can also be used with date input values. There are a lot of similar functions, but the ROUND function is probably the most common and it’s pretty easy to use. The purpose of the Oracle ROUND function is to take a number and round it to the specified number of decimal places. Let’s take a look at the ROUND function and some examples. WITH RECURSIVE summary_stats AS ( SELECT ROUND( AVG(duration_minutes), 2) AS mean, PERCENTILE_CONT(0.5) WITHIN GROUP ( ORDER BY duration_minutes) AS median, MIN(duration_minutes) AS min, MAX(duration_minutes) AS max, MAX(duration_minutes) - MIN(duration_minutes) AS range, ROUND( STDDEV(duration_minutes), 2) AS standard_deviation, ROUND( VARIANCE(duration_minutes), 2) AS variance, PERCENTILE_CONT(0.25) WITHIN GROUP ( ORDER BY duration_minutes) AS q1, PERCENTILE_CONT(0.The Oracle ROUND function is one of those functions that is used a lot and performs similar in many languages. In the below query, we’ll create two CTEs namely summary_stats (which returns the previously discussed statistics one per each column) and row_summary_stats (which returns the statistics one per each row). We’ll put all the functions discussed earlier together and return them in a single table.
