How to not round values for a division with variables in SAS

I have two numeric variables in SAS:

%let var1=10;
%let var2=8;

I have to do the division between the two, but if I do:

%let var3=%eval(&var2/&var1);
%put &var3;

the result is 0. Because var2 is a subset of var1 and by default the system rounds the number to 0. In fact if I do &var1/&var2 the result is 1.

Given that I have to use this value for a percent I have the need that it is maintained with the decimal.

How can I overcome this?

You need to use %SYSEVALF() if you want something other than integer arithmetic.

Macro code is for generating text. If you really need to do calculations you should do it in a data step.
