ROUND

The ROUND() function rounds a fact or metric to the number of decimal places specified in the second parameter. If the second parameter is not specified, then the function rounds to the nearest integer.

The input value is rounded to an integer (by default) or to a defined number of decimal points. This function allows metric builds to retain exact levels of precision throughout a set of calculations.

  • The first input value can be any constant, fact, metric, or metric expression.
  • The optional second parameter defines the number of decimal points to which the function applies rounding. This parameter should be an integer, although real numbers are supported for input.

Syntax 

SELECT ROUND(…)
ROUND(fact)
ROUND(metric)
ROUND(metric_expression)
ROUND(input, number_of_decimal_places)
