Long-float operators

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

      Operator       Operation       Example
$$$ the long-float ($$$ 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 long-float coercion: 

  (setf x (coerce$$$ x))
