How to remove scientific notation in a column¶
Formatting numbers can often be a tedious data cleaning task.
It can be made easier with the format() function of the Dataiku DSS Formula language. This function takes a printf format string and applies it to any value.
Format strings are immensely powerful, as they allow you to truncate strings, change precision, switch between numerical notations, left-pad strings, pad numbers with zeros, etc. More specifically, Dataiku DSS formulas use the Java variant of format strings.
For example, you may have a column of very small numbers represented in scientific notation. If instead you wanted to convert this column to 5 decimal places, you can use:
format("%.5f", my_column_name)
