The Short-Integer Format

When you use the correct short-integer format for your data, you do not see any difference in how the numbers appear. However, the numbers occupy less disk space and use less memory. Short-integer formats must be activated in preferences to appear in the Column Info window.

To make short-integer formats available in the Column Info window

1. Select File > Preferences and click Tables.

2. Select the Allow short numeric data format option.

3. Click OK to return to the data table.

To store numeric data in short-integer format:

1. Double-click above the column name whose values you want to be short-integer.

The Column Info window appears.

2. From the Data Type menu, select 1-byte integer, 2-byte integer, or 4-byte integer.

JMP stores values as integers in the range that you selected. The following numbers are examples:

For 1-byte integer, the range of numbers that you can enter is from -126 to 127.

For 2-byte integer, the range of numbers that you can enter is from -32,766 to 32,767.

For 4-byte integer, the range of numbers that you can enter is from -2,147,483,646 to 2,147,483,647.
