Test Functions
The test functions are
logical
operators that always return
either a
1
(true')
or a
0
(false).
<■
Less than. Returns 1 if true, 0 if false.
value Kaalue2
^
Less than or equal to. Returns 1 if true, 0 if false.
value l^value2
— —
Equals (logical test). Returns 1 if true, 0 if false.
value 1 = =value2
Not equal to. Returns 1 if true, 0 if false.
i=
value! i=value2
>
Greater than. Returns 1 if true, 0 if false.
value I>value2
>
Greater than or equal to. Returns 1 if true, 0 if false.
value! ^value2
AND
IFTE
NOT
OR
XOR
Compcires
value!
and
value2.
Returns 1 if they cire both non
zero, otherwise returns
0
.
value!
AND
value2
If
expression
is true, do the
trueclause;
if not, do the
falseclause.
IFTE
(
expression, trueclause, falseclause)
Example: IFTE(X>
0
,x^x’)
Returns 1 if
value
is zero, otherwise returns 0.
NOT
value
Returns 1 if either
value!
or
value2
is non-zero, otherwise
returns
0
.
value!
OR
value2
Exclusive OR. Returns 1 if either
value!
or
value2
—but not both
of them—is non-zero, otherwise returns
0
.
value!
XOR
