Set-theoretic operations on intervals
In general, a binary operation
X Y op
where
X
and
Y
are intervals is the set
{x op y forall x in X, y in Y}
.
Binary operations on intervals:
interval+
( i1 i2 -- i3 )
interval-
( i1 i2 -- i3 )
interval*
( i1 i2 -- i3 )
interval/
( i1 i2 -- i3 )
interval/i
( i1 i2 -- i3 )
interval-mod
( i1 i2 -- i3 )
interval-rem
( i1 i2 -- i3 )
interval-min
( i1 i2 -- i3 )
interval-max
( i1 i2 -- i3 )
Bitwise operations on intervals:
interval-shift
( i1 i2 -- i3 )
interval-bitand
( i1 i2 -- i3 )
interval-bitor
( i1 i2 -- i3 )
interval-bitxor
( i1 i2 -- i3 )
Unary operations on intervals:
interval-1+
( i1 -- i2 )
interval-1-
( i1 -- i2 )
interval-neg
( i1 -- i2 )
interval-bitnot
( i1 -- i2 )
interval-recip
( i1 -- i2 )
interval-2/
( i1 -- i2 )
interval-abs
( i1 -- i2 )
interval-log2
( i1 -- i2 )
