By default, numbers are treated as integers, but you can set the number of fraction digits to retain and display by setting the variable scale like this:

 scale=0
 1/3
 0
 scale=5
 1/3
 .33333

As you might guess from this, you can assign values to other variables, and use them in calculations like this:

 foo=1/3
 foo*3
 .99999
