Operator Function

Mathematical

+ Add INT/FP X +Y Adds the right operand to the left operand.

– Subtract INT/FP X – Y Subtracts the right operand from the left operand.

Multiply INT/FP

Multiplies the left operand by the right operand.

/ Divide INT/FP X / Y Divides the left operand by the right operand.

Unary minus INT/FP

± X

When placed to the immediate left of an operand, it

negates the numeric value of the operand.

% Modulo INT/FP X % Y

Produces the whole number remainder of the division

of the left operand by the right operand.

ABS Absolute value INT/FP ABS(X)

Produces the absolute value of the listed operand

(negates the value if it is negative).

SQ Square INT/FP SQ(X) Computes the square of the listed operand.

SQR Square root FP SQR(X) Computes the square root of the listed operand.

DST Distance FP

DST(X

Computes distance from a point A to a point B – given

four listed coordinate operands X

, Y

, X

, and Y

– by

computing the square root of the sum of the squared

differences (X

–X

and Y

–Y

SIN Sine FP SIN(X)

Computes the sine of a listed operand (angle –

assumed in degrees). Returns a fixed point number.

COS Cosine FP COS(X)

Computes the cosine of a listed operand (angle –

assumed in degrees). Returns a fixed point number.

TAN Tangent FP TAN(X)

Computes the tangent of a listed operand (angle –

assumed in degrees). Returns a fixed point number.

ARC

Arc (prefix to

SIN, COS, or

TAN)

SIN

ARC COS (X)

TAN

ARC combines with SIN, COS, or TAN function, to

create the respective inverse function – arcsine,

arccosine, or arctangent. These inverse functions

produce an angular result (in degrees).

Logical

AND Logical AND INT/FP X AND Y

Produces a “1” result if both the left and right operands

are nonzero; otherwise, produces a “0” result.

OR Logical OR INT/FP X OR Y

Produces a “1” result if either the left or right operand

is nonzero; otherwise, produces a “0” result.

NOT Logical NOT INT/FP NOT X

Used to invert a logical value – Produces a “0” result if

the operand is nonzero; produces a “1” result if

operand is 0.
