![]() ![]() Here the value of W.D is 10.2, which means SAS reads a total of 10 spaces. Let's understand through an example, how we can display data by using W.D format.Īs we can see in the output, SAS is using W.D informat to store numeric values. It is the basic reading, and also an output format of SAS, where W is the number of columns and D is the number of digits on the right side of the decimal place. We can display numeric values in three formats: It is another part of the SAS numeric format. SAS Output Format is used to instruct the SAS to display data in the desired format in the output. It allocates 7 spaces for the digits that are left the side of the decimal, 1 space for the decimal and remaining 2 for the digits that are the right side of the decimal. Here the value of W.D is 10.2, which means that SAS reads a total of 10 spaces. *maximum number of columns*/Īs we can see in the output, SAS is following W.D informat to store numeric values. We can use W.D informat in SAS programs by using the following Syntax: It demonstrates how the allocation of digits takes place in the SAS system by using W.D informat. In the following table, numeric data 2789.93 is demonstrated by using 7.2 informat. Four spaces will be allocated for the left side digits of the decimal, one space for the decimal and remaining two for the right side digits of the decimal. In W.D, W is the number of columns, and D is the number of digits on the right of the decimal place.įor example, if the value of W.D is 7.2, then it will allocate a total of 7 spaces for the output. The SAS system is based on floating-point representation referred to as W.D to read the numeric informat. ![]() SAS Numeric Informat consists of two components one is Number of Columns in output, and another is Number of Decimal Places. It represents the maximum "W" number of columns with "D" decimal places. ![]() It represents the maximum "W" number of columns with no decimal places. The informat instructs SAS, how to read data into SAS variables.įollowing is a list of informats which are used to read the data into SAS. Always place a decimal (.) at the end of the informat because SAS uses this decimal (.) to separates informat from other variables. These are specified in the INPUT statement. SAS informat is a part of the SAS Numeric Format, specifies how SAS reads a particular data. Let's understand the following terms of numeric formats in detail: The list of all internal informats and output formats can be seen by typing ' help format' in the command line and then clicking ' SAS Format and Informat' in the resulting window. Or user-defined informats and output formats can be created by using PROC FORMAT. There are many internal informats and output formats in SAS. Where an informat is a specification of how SAS should read data, and an output format is a layout specification of how a variable should be displayed in the output. SAS uses two types of numeric formats, one is informat, and another is output format. These formats are used at the end of the variable name to apply a specific numeric format to the data. SAS can handle different types of numeric data formats. ![]()
