= =

Equals (logical test). Returns 1 if true, 0 if false.

 

value1==value2

≠

Not equal to. Returns 1 if true, 0 if false.

 

value1≠value2

>

Greater than. Returns 1 if true, 0 if false.

 

value1>value2

≥

Greater than or equal to. Returns 1 if true, 0 if false.

 

value1≥value2

AND

Compares value1 and value2. Returns 1 if they are both

 

non-zero, otherwise returns 0.

 

value1 AND value2

IFTE

If expression is true, do the trueclause; if not, do the

 

falseclause.

 

IFTE(expression, trueclause, falseclause)

 

Example

 

IFTE(X>0,X2,X3)

NOT

Returns 1 if value is zero, otherwise returns 0.

 

NOT value

OR

Returns 1 if either value1 or value2 is non-zero, otherwise

 

returns 0.

 

value1 OR value2

XOR

Exclusive OR. Returns 1 if either value1 or value2—but

 

not both of them—is non-zero, otherwise returns 0.

 

value1 XOR value2

Trigonometry functions

 

The trigonometry functions can also take complex

 

numbers as arguments. For SIN, COS, TAN, ASIN,

 

ACOS, and ATAN, see the Keyboard category.

ACOT

Arc cotangent.

 

ACOT(value)
