Constants Functions

The Calculator adapter supports the following constants functions:


`e()`	Base of natural logarithms
`pi()`	Ratio of the diameter to the circumference of a circle

Arithmetic Functions

The Calculator adapter supports the following arithmetic functions:


`abs(x)`	absolute value
`ceil(x)`	smallest integer greater than or equal to x
`exp(x)`	E to the power
`fact(i)`	factorial
`floor(x)`	largest integer less than or equal to x
`ln(x)`	natural logarithm
`log10(x)`	log base 10
`power(x, y)`	power
`rand()`	random number 0..1
`round(x)`	round to integer
`sqrt(x)`	square root

Statistical Functions

The statistical functions take an arbitrary number of scalar arguments and return a single scalar value.


`sum(x, y,...)`	sum
`max(x, y,...)`	maximum
`min(x, y,...)`	minimum
`absSum(x, y,...)`	sum of absolute values
`absMax(x, y,...)`	maximum absolute value

`mean(x, y,...)`	mean
`stdDev(x, y,...)`	standard deviation

Logical Functions

The Calculator adapter supports the following logical functions:


`true()`	logical true
`false()`	logical false
`if(b, x, y)`	conditional (if b then x else y)

Trigonometry Functions

Trigonometry functions are in radians. Use the expression degrees / 180 * pi() to convert degrees to radians. The Calculator adapter supports the following trigonometry functions:

`tan(x)`	tangent

Inverse Trigonometry Functions

Inverse Trigonometry functions are in radians. Use the expression degrees / 180 * pi() to convert degrees to radians. The Calculator adapter supports the following inverse trigonometry functions:


`acos(x)`	arc cosine
`acot(x)`	arc cotangent
`acsc(x)`	arc cosecant
`asec(x)`	arc secant
`asin(x)`	arc sine
`atan(x)`	arc tangent

Hyperbolic Functions

The Calculator adapter supports the following hyperbolic functions:
