In fuzzy logic, truth values range from 0 to 1.

The logical functions "and", "or", etc., are floating-point functions
that combine two truth-values to get another truth-value.

So "if Joe is tall and gangly" might be rendered in FORTRAN as
  
  IF (AND(TALL(JOE),GANGLY(JOE))>0.5) ...

That is: If the AND function, applied to TALL(JOE) and GANGLY(JOE),
yields a value greater than 0.5, then...

(where TALL(JOE) and GANGLY(JOE) would each give a floating-point value
between 0 and 1).
