Macro Variables Remove Decimal

I have several macro variables that represent a numeric value.  I understand that macro variables are character strings, so I can't format them as I could a number.  I want the variables to display to 1 decimal point, but there are some that only an integer.  For example, I want the value "1" to display as "1.0".  I am trying to add the string ".0" to any variable that represents an integer.  The code below does not work.  It likes to remove the decimal and display "10" instead of "1.0".  Any ideas on how to retain the decimal point?

%let zerodec=%quote(.0);

%put ~~~&zerodec.~~~;

%let dose1=1;

%let dose1=%sysfunc(cat(&dose1.,%quote(&zerodec.)));

%put ~~~&dose1.~~~;

dose1 = %sysfunc(putn(&dose1,f3.1));

A macro value that will resolve to a number can be "formatted" using PUTN (not just PUT)

What about?

%let str=1;

%let str=%sysfunc(inputn(&str,best32.),16.1);

%put str: &str;

Result:

str: 1.0
