Using mathematical functions
Compares value1 and value2. Returns 1 if they are both non-
zero, otherwise returns 0.
value1 AND value2
If expression is true, do the trueclause; if not, do the
falseclause.
IFTE(expression , trueclause , falseclause )
Example
2 3
IFTE(X>0,X ,X )
Returns 1 if value is zero, otherwise returns 0.
NOT value
Returns 1 if either value1 or value2 is non-zero, otherwise
returns 0.
value1 OR value2
Exclusive OR. Returns 1 if either value1 or value2—but not
both of them—is non-zero, otherwise returns 0.
value1 XOR value2
The trigonometry functions can also take complex numbers as
arguments. For SIN, COS, TAN, ASIN, ACOS, and ATAN,
see the Keyboard category.
