The BEST format is for converting numbers into strings that will best fit the width provided. But your program is trying to use the BEST informat instead of the BEST format. Informats are used to convert strings into values. Numeric informats convert strings into numbers.
Simply so, How do I convert numeric to SAS?
To convert numeric values to character, use the PUT function: new_variable = put(original_variable, format.); The format tells SAS what format to apply to the value in the original variable. The format must be of the same type as the original variable.
Similarly, What is SAS date value?
SAS date values are the stored internally as the number of days between January 1, 1960, and a specified date. Dates after January 1, 1960, are stored as positive numbers; dates before January 1, 1960, are stored as negative numbers.
What does best do in SAS?
When a format is not specified for writing a numeric value, SAS uses the BESTw. format as the default format. The BESTw. format attempts to write numbers that balance the conflicting requirements of readability, precision, and brevity.
Furthermore, What does DW mean in SAS?
A data warehouse (or enterprise data warehouse) stores large amounts of data that has been collected and integrated from multiple sources.

How do you keep leading zeros in SAS?
To add leading zeros in SAS, all you have to do is to add a z format to the variables. The Z format writes a standard numeric data with leading 0s. w specifies the width of the value. TIP: Give enough width to for the value including the decimal point or a minus sign, if necessary.
How do you remove leading zeros in SAS?
Use Pattern Recognition to Remove Leading Zeros
You can use pattern recognition (the PRXCHANGE function in SAS) to specify a string you want to remove from a larger string. For example, leading zeros.
How do I use substr in SAS?
The SAS data step function SUBSTR (commonly pronounced “sub- string”) function is used to work with a specific position or positions of characters within a defined character variable. The function focuses on a portion of a string and can go on either side of the “=” sign in a data step statement.
What is SAS time?
The Definition of a SAS Time and Datetime
Specifically, SAS stores time as a numeric value equal to the number of seconds since midnight. So, for example, SAS stores: a 60 for 12:01 am, , since it is 60 seconds after midnight. a 95 for 12:01:35 am, since it is 95 seconds after midnight.
How does SAS store dates?
SAS dates are stored as simple integer numbers. SAS time/datetimes are stored as decimal numbers to include 10th and 100th of seconds. For time values the integer part is the number of seconds from midnight. For datetime the integer part equals the number of seconds from January 1,1960.
How do you calculate age in SAS?
age = floor ((intck(‘month’,birthday,today) – (day(today) < day(birthday))) / 12); The intck function will correct for leap years. The first part of the command, intck(‘month’,birthday,today) , returns the number of times the first day of a month is passed between birthday and today.
What does BEST12 mean in SAS?
refers to the instructions that SAS uses when printing variable values. If no format is specified, the default format is BEST12. … refers to the instructions that SAS uses when reading data values. If no informat is specified, the default informat is w.d for a numeric variable, and $w. for a character variable.
How do you remove leading blanks in SAS?
The advantage of using the STRIP function is that it runs faster than TRIM(LEFT) or TRIMN(LEFT) (SAS OnlineDoc® 9.1. 3). If you have a large data set, it is recommended to use the STRIP function to remove leading and trailing blanks. Another useful function to deal with blanks is the COMPRESS function.
How do I use the round function in SAS?
ROUND is the function name; argument is the numeric value or variable you want to have rounded; and rounding-unit is the unit that you want to result to be rounded to (e.g. 10, 100, 0.1, 0.01, 5, etc.) For example, ROUND(34.58, 0.1) tells SAS to round the number 34.58 to the nearest tenth. SAS will return 34.6.

How do you use length in SAS?
The LENGTH function returns the length of a character string in characters, excluding trailing blanks, whereas the LENGTHM function returns the amount of memory in bytes that is allocated for a character string. LENGTH always returns a value that is less than or equal to the value returned by LENGTHM.
How do you rename in SAS?
You rename a SAS variable with the RENAME option. The RENAME option is a data set option which enables you to change the name of a variable. First of all, you define the old variable name, then an equal sign, and finally the new variable name. You can rename one or more variables with one RENAME option.
What is coalesce in SAS?
The COALESCE function checks the value of each expression in the order in which they are listed and returns the first non-null or nonmissing value. If only one value is listed, then the COALESCE function returns the value of that argument.
How do I remove a space in SAS?
Sometimes, a string variable can have many words in it and extra spaces between the words. The easiest way to get rid of the extra spaces is to use SAS function compbl.
How do I trim in SAS?

How do you input in SAS?
The INPUT function returns the value produced when a SAS expression is converted using a specified informat. You must use an assignment statement to store that value in a variable. The INPUT statement uses an informat to read a data value. Storing that value in a variable is optional.
