Double-float operators

These double-float declared-numeric operators are defined in the :gbbopen-tools module:

      Operator       Operation       Example
$$ the double-float ($$ x)
+$$ + (+$$ x y z)
-$$ - (-$$ x y z)
1+$$ 1+ (1+$$ x)
1-$$ 1- (1-$$ x)
*$$ * (*$$ x y z)
/$$ / (/$$ x y z)
=$$ = (=$$ x y z)
/=$$ /= (/=$$ x y z)
<$$ < (<$$ x y z)
<=$$ <= (<=$$ x y z)
>$$ > (>$$ x y z)
>=$$ >= (>=$$ x y z)
abs$$ abs (abs$$ x)
bounded-value$$ bounded-value (bounded-value$$ x y z)
ceiling$$ ceiling (ceiling$$ x divisor)
decf$$ decf (decf$$ x delta)
decf-$$after decf-after (decf$$-after x delta)
decf/delete$$-acons decf/delete-acons (decf/delete$$-acons
    x delta alist)
evenp$$ evenp (evenp$$ x)
fceiling$$ fceiling (fceiling$$ x divisor)
floor$$ floor (floor$$ x divisor)
ffloor$$ ffloor (ffloor$$ x divisor)
fround$$ fround (fround$$ x divisor)
ftruncate$$ ftruncate (ftruncate$$ x divisor)
incf$$ incf (incf$$ x delta)
incf$$-after incf-after (incf$$-after x delta)
max$$ max (max$$ x y z)
min$$ min (min$$ x y z)
minusp$$ minusp (minusp$$ x)
mod$$ mod (mod$$ x divisor)
oddp$$ oddp (oddp$$ x)
plusp$$ plusp (plusp$$ x)
pushnew/incf$$-acons pushnew/incf-acons (pushnew/incf$$-acons
    'x delta alist)
round$$ round (round$$ x divisor)
truncate$$ truncate (truncate$$ x divisor)
zerop$$ zerop (zerop$$ x)

The one-argument function coerce$$ provides convenient double-float coercion: 

  (setf x (coerce$$ x))
