Truncate

Use trunc() to examine the distributions of attributes of the Fortune 500 companies.

Remember that trunc() truncates numbers by replacing lower place value digits with zeros:

trunc(value_to_truncate, places_to_truncate)

Negative values for places_to_truncate indicate digits to the left of the decimal to replace, while positive values indicate digits to the right of the decimal to keep.
