Pyspark absolute value

SparkSession pyspark.

The abs function in PySpark is used to compute the absolute value of a numeric column or expression. It returns the non-negative value of the input, regardless of its original sign. The primary purpose of the abs function is to transform data by removing any negative signs and converting negative values to positive ones. It is commonly used in data analysis and manipulation tasks to normalize data, calculate differences between values, or filter out negative values from a dataset. The abs function can be applied to various data types, including integers, floating-point numbers, and decimal numbers. It can also handle null values, providing flexibility in data processing and analysis.

Aggregate functions operate on a group of rows and calculate a single return value for every group. All these aggregate functions accept input as, Column type or column name in a string and several other arguments based on the function and return Column type.
