C provides several different types of numeric variables. You need different types of variables because different numeric values have varying memory storage requirements and differ in the ease with which certain mathematical operations can be performed on them. Small integers (for example, 1, 199, and...
You can check the data type of a variable using any of these commands. Display Format for Numeric Values Use theformatfunction or set Preferences to control the display of numeric values. Combining Unlike Integer Types If you combine different integer types in a matrix (e.g., signed with uns...
If you are new to mainframe computing, you might not recognize two common types of numeric variables in COBOL: zoned decimal and packed decimal. If you work with these types, your EGL data types must match the format and sign configuration of the data these types contain. Here is a quick...

are numeric variables and containonly numbers. However, values such as “26-jan-2015” sure don'tlooklike numbers, do they? This is because SPSS candisplaynumbers in very different ways. These ways of displaying data values are referred to asvariable formats. ...
Number data types store numeric values. Number objects are created when you assign a value to them. For example − var1 = 1 var2 = 10 You can also delete the reference to a number object by using the del statement. The syntax of the del statement is − del var1[,var2[,var3...
