#### Mathematical Functions

ABS

ABS Absolute Value: ABS(<Double>)
Returns absolute value of input.

EXP

EXP Exponential: EXP(<Double>)
Returns the exponential of the expression.

LOG

LOG Log Base 10: LOG(<Double>)
Returns the log base 10 of the expression.

LN

LN Natural Log: LN(<Double>)
Returns the natural logarithm of the expression.

ROUND

ROUND Rounding: ROUND(<Double>)
Returns the input rounded to the nearest integer.

SQRT

SQRT Square Root: SQRT(<Double>)
Returns the square root of the input.

Trigonometry Functions

Important: Each of the trigonometry functions by default takes and returns radians. If you want values in degrees, use the RAD2DEG function described below.

ACOS

ACOS ArcCosine: ACOS(<Double>)
Returns the arc cosine of the expression. For example, ACOS(5.0) returns 0. In general, ACOS(<expression>) returns the arc cosine of the value of the expression.

ASIN

ASIN ArcSine: ASIN(<Double>)
Returns the arc sine of the input.

ATAN

ATAN ArcTangent: ATAN(<Double>)
Returns the arc tangent of the input.

COS

COS Cosine: COS(<Double>)
Returns the cosine of the input.

DEG2RAD

DEG2RAD Degrees to Radians: DEG2RAD(<Double>)
Returns the input divided by 360 and multiplied by 2p. Converts from degrees to radians.

RAD2DEG

RAD2DEG Radians to Degrees: RAD2DEG(<Double>)
Returns the input multiplied by 360 and divided by 2p. Converts from radians to degrees.

SIN

SIN Sine: SIN(<Double> )
Returns the sine of the input.

TAN

TAN Tangent: TAN(<Double>)
Returns the tangent of the input.

Note: Functions where the input is out of range (i.e., for ACOS, ASIN, LOG, LN, SQRT etc. that would cause the computer to crash) return 0.
