Question

Under the Units field in the Basic Variables documentation, most of the units per variable are pretty straight forward, but there are some that have “64” or “_32” after the unit designator for example. Is there documentation with an explanation?

Answer

This is from the Allocate Help:

Units- The Units drop down allows you to control how the values for your new variable will be displayed when you output them.Acceptable Unit options include Dollars, Integers, and Percentages.

Round 10Input number magnitude may exceed MAX_LONG. Input will be rounded to nearest 10. Handles numbers up to up to 20 billion. On retrieval will have a zero in the 10's place. Allocate stores all input numbers as long, so we need to lose a place of accuracy to store numbers greater than MAX_LONG (2 billion).Whole, rounded to 10's
Round 100Same as Round 10, handles numbers to 200 billion and rounds last two digits to zeroWhole, rounded to 100's
Round 1,000Same as Round 10, handles numbers to 2,000 billion and rounds last three digits to zeroWhole, rounded to 1,000's
