Hi I am trying to create this simple macro to compute an expression after doing a floating point number comparison ... %macro calc_val(x,y);      %if &x < &y %then <expression 1>;      %else <expression 2>; %mend calc_val; /* initiate macros */ %let b = 23.6; %calc_val(32.5, &b) run; The code is running but it is not doing it properly. In the above example, the SAS log file is saying   SYMBOLGEN: Macro variable X resolves to 32.5 SYMBOLGEN: Macro variable Y resolves to B MLOGIC(CALC_VAL): %IF condition &x < &y is TRUE Hence it is computing expression 1 instead it should have gone to compute expression 2. Where am I going wrong? ... View more
