The SAS system writes the number in the total of W spaces, one space for decimal and D spaces for the numbers of decimals. Simple W.D format: described in the above example of 8.2 formats.There are 3 common types of SAS Output formats for displaying numeric data: Now, say we want only 2 digits after the decimal, again we would have to specify in the informat the no. In that case, it would look like this – $3,467.201 He would want to have commas after every 3 digits, to get a better understanding. Now, consider somebody who reads this as three thousand four hundred and sixty-seven dollars. For this, we would have to use an informat to instruct SAS that we want to read this salary in terms of dollars. Now, a person reading this look at this salary in terms of dollars, so we would want to place a dollar sign before it. It is another component of SAS Numeric Format.Įxample – If there is a salary column in our dataset, salary being a numeric data type will have decimal places in it. SAS Output Format is an instruction for displaying data in SAS. Maximum “n” number of columns with “p” decimal places which removes any comma or dollar signs. Maximum “n” number of columns with “p” decimal points. Maximum “n” number of columns with no decimal point. In the below table, numeric data 12345.66 is demonstrated how to allocate digits and decimal in the SAS system using 8.2 formats. One space will be for the decimal and 2 for the digits to the right of the decimal this will leave 5 spaces for the digits to the left of the decimal. The SAS system uses floating-point representation referred to us as W.D, where W is the width and D is the number of digits to the right of the decimal place.Īs an example, 8.2 will allocate a total of 8 spaces for the output. The number of columns (width) v of the output and the number of decimal places. There are two components in a SAS numeric format. There are different types of SAS informat available depending upon the data type of variable. d is the number of digits to the right of the decimal.w is the maximum number of columns that can be stored with the variable.Format_name is the name we wish to give to the informat variable.Variable_name is the name of the variable that will be read using the informat.The informat instructs SAS on how to read data into SAS variables. They are specified in the INPUT statement while defining variables.Ī decimal (.) is always placed at the end of the informat and that is how SAS differentiates it from other variables. SAS informat is one of the components of SAS Numeric Formate, specify how we wish to read a particular data. At last, we will discuss syntax of Informat and output format of SAS Numeric format. Moreover, how SAS Numeric format & types of numeric formats used in a program to meet our needs. Today we will be learning about the SAS Numeric Format, types of Numeric Format in SAS Programming Language: SAS Informat and SAS Output Formats. We read in the earlier tutorials that while defining a variable, it is sometimes required that we specify a SAS format for the same.
