Compare Numbers between variable MACRO

[Abud]

Hi all,

I'm trying to compare two variables macro (price_trd vs max_price) however as the example below that's not happening....

Please someone could give me a little help ?

%let price_trd = 93.68;

%put &price_trd.;

%let max_price = 100.94;

%put &max_price.;

%macro test;

  %if  &price_trd. < &max_price %then %do;

  %put Pass HERE;

  %end;

%mend;

%test;

Need to use %SYSEVALF() to do floating point calculations, otherwise macro will attempt to use %EVAL() which only does integer math.

Wrap the comparison in %sysevalf

E.G.

  %if  %sysevalf(&price_trd. LT &max_price) %then %do;

As always in the fine print (floating point arithmetic vs integer for %eval).
