Computes the largest integer that is not more than the input value. Input can be an Integer, a Decimal, a column reference, or an expression.
Wrangle vs. SQL: This function is part of Wrangle, a proprietary data transformation language. Wrangle is not SQL. For more information, see Wrangle Language.
Basic Usage
Numeric literal example:
floor(2.5)
Output: Returns the value 2.
Expression example:
floor(MyValue + 2.5)
Output: Returns the largest integer that is less than the sum of 2.5 and the value in the MyValue column.
