You can use the **Z **format option in SAS to add leading zeros to numeric values.

The following examples show how to use the **Z **format option in practice with the following dataset in SAS that shows the total sales made by various employees at some company:

**/*create dataset*/
data my_data;
input employee $ sales;
datalines;
A 32
B 10
C 24
D 40
E 138
F 42
G 54
H 9
I 38
J 22
K 18.5
;
run;
/*view dataset*/
proc print data=my_data;
**

**Example 1: Use Z Format with No Decimal Places**

We can use the following **Z** format option to add as many leading zeros as necessary to make each value in the **sales** column have a length of 6:

**/*use Z format to add leading zeros to values in sales column*/
proc print data=my_data;
format sales z6.;
run;**

Each value in the **sales **column now has as many leading zeros as necessary for it to have a length of 6.

Since we didn’t specify any value after the decimal place in **z6.** we told SAS not to display any values after the decimal place and to simply round each value to the nearest integer.

For example, the last value in the **sales** column had a value of **18.5** but was rounded to **19** and then had leading zeros added to it in order to create the final value of **000019**, which has total length of 6.

**Example 2: Use Z Format with Decimal Places**

We can use the following **Z** format option to add as many leading zeros as necessary to make each value in the **sales** column have a length of 10, including 1 decimal place:

**/*use Z format to add leading zeros to values in sales column*/
proc print data=my_data;
format sales z10.1;
run;**

Each value in the **sales **column now has as many leading zeros as necessary for it to have a length of 10.

Since we used **z10.1** we told SAS to display one value after the decimal place of each value.

Also note that the total length of **10** includes the decimal point and the value after the decimal point.
