round problem

frenchy_robert — Sat, 06 Oct 2012 10:26:42 GMT

Hello, i'm a beginner in SAS, and i have a problem with the function ROUND !

If I create toto table :

data toto;

input Annee Note Bac $; /* JAMAIS d'accent */

cards;

97 12.025 A

98 13.075 A

97 9.045 B

98 8.250 A

97 7.685 C

98 10.554 C

97 14.895 B

;

run;

then i want to print only Note var with rounding !

so :

title "Exemple d'édition de certaines variables";

proc print data=toto noobs round;

var note bac;

run;

it gives a 0.01 default rounding

but what if i want a 0.1 roundinf for example ?

i have so many syntax errors that i'm a bit upset now

thanks

You must associate a format to the variable, with the statement :

format note 6.1;

If you insert that statement in your datastep, the format will be permanently associated to the variable. If you put the format statement in the proc print call it will be associated only for the duration of the procedure.

Ok thanks to you two

Now it works !

Can you explain me the meaning of 4.1 or 6.1 ? Is there a number for each rounding ?

in format 6.1, or more generally w.d, w is the width of the field and d is the number of decimals. Check

http://support.sas.com/documentation/cdl/en/leforinforref/63324/HTML/default/viewer.htm#n1n7bmvs1brl23n1dj9cbzau39df.htm

there are LOTS of formats available.
