Hi, I have two macro variables &a and &b. I have to sum these two macro variables and assign it to other macro variable name &c. How do I do that? Please help me.
%let a=1.4;
%let b=1.6;
%let c=%sysevalf(&a+&b);
%put &=c;
%eval works only on integers. If &b has a value of 7.5, you get an error. In that case, you could use %sysevalf
but you'd still be better off doing anything more advanced than integer arithmetic in a data step
a and b will have decimal values too. can you help me the statement for that part too?
He did, %SYSEVALF.

Do the math in a data step
%let a=1.4;
%let b=1.6;
%let c=%sysevalf(&a+&b);
%put &=c;
Thanks guys. it worked.
