1 MARK CARPENTER, Ph.D. Module 5 : SAS Functions Introduction to SAS Programming and Applications Descrip(on. In this module, we with various SAS Func7ons, including numerical func7ons, date func7ons and character func7ons. SAS Keywords : Date, Day, Year, Month, COMPBL, COMPRESS, FIND New Topics New PROCs : Character and Date Functions : N/A Thursday, Sep 24, viewer.htm#a htm

2 DATE/TIME FUNCTIONS: DATE Func(on DATE Func(on Returns the current date as a SAS date value. Category: Date and Time Alias: TODAY See: TODAY Func7on DATE() en/ viewer.htm#a htm

3 DATE/TIME FUNCTIONS: DAY Func(on DAY Func(on Returns the day of the month from a SAS date value. Category: Date and Time Details Examples See Also viewer.htm#a htm DAY(date) date specifies a SAS expression that represents a SAS date value.

4 TRUNCATION FUNCTIONS: ROUND Func(on ROUND Func(on Rounds the first argument to the nearest mul(ple of the second argument, or to the nearest i when the second argument is omiked. Category: Trunca7on Details Basic Concepts Differences between Binary and Decimal Arithme7c The Effects of Rounding Expressing Binary Values Tes7ng for Approximate Equality Producing Expected Results When the Rounding Unit Is the Reciprocal of an Integer Compu7ng Results in Special Cases Compu7ng Results When the Value Is Halfway between Mul7ples of the Rounding Unit ROUND (argument <,rounding- unit>) viewer.htm#a htm

5 TRUNCATION FUNCTIONS: FLOOR Func(on FLOOR Func(on Returns the largest integer that is less than or equal to the argument, fuzzed to avoid unexpected floa(ng- point results. Category: Trunca7on FLOOR (argument) viewer.htm#a htm argument specifies a numeric constant, variable, or expression.

6 CHARACTER FUNCTIONS: COMPBL Func(on COMPBL Func(on Removes mul(ple blanks from a character string. Category: Character COMPBL(source) viewer.htm#a htm source specifies a character constant, variable, or expression to compress. The Basics: The COMPBL func7on removes mul7ple blanks in a character string by transla7ng each occurrence of two or more consecu7ve blanks into a single blank.

7 CHARACTER FUNCTIONS: COMPRESS Func(on COMPRESS Func(on viewer.htm#a htm Returns a character string with specified characters removed from the original string. Category: Character Restric(on: I18N Level 0 Tip: DBCS equivalent func7on is KCOMPRESS in SAS Na(onal Language Support (NLS): Reference Guide. COMPRESS(<source><, chars><, modifiers>)

8 running head Introduction to SAS Programming and Applications CHARACTER FUNCTIONS: FIND Func(on FIND Func(on: Searches for a specific substring of characters within a character string. Category: Character FIND(string,substring<,modifiers><,startpos>) FIND(string,substring<,startpos><,modifiers>) hjp://support.sas.com/documenta7on/cdl/ en/ viewer.htm#a htm string specifies a character constant, variable, or expression that will be searched for substrings substring is a character constant, variable, or expression that specifies the substring of characters to sear for in string. modifiers is a character constant, variable, or expression that specifies one or more modifiers. The follow modifiers can be in uppercase or lowercase:

9 CHARACTER FUNCTIONS: SUBSTR Func(on SUBSTR (ley of =) Func(on Replaces character value contents. Category: Character viewer.htm#a htm SUBSTR(variable, posi7on<,length>)=characters- to- replace hjp://support.sas.com/documenta7on/cdl/ en/ Variable: specifies a character variable. Posi3on: specifies a numeric constant, variable, or expression that is the beginning character posi7on. Length: specifies a numeric constant, variable, or expression that is the length of the substring that will be replaced.
