* Functions use radians (2
Example 1: if P1 was measuring degrees C the expression P1 = damp[A1, P1, 3] will damp
the signal with changes up to 3 degrees C, any change over 3 degrees between readings
will be damped but by a small amount.
Example 2: P5 = damp[A2, P5, A3] will damp the A2 input up to a level determined by input
A3, note the reference parameter (P5) is always the same as the pen it is being used in, this
should always be the case.

Syntax
cosh[x] Returns the Hyperbolic COSINE of x
damp[x,y,z] x = input, y = Pen (pen variable being used)
and z = damping limit in engineering units.
See "Damping examples:" on
page 236.
/ Returns the result of the division
eval[x] Returns 1 if x is non zero, otherwise returns
zero
exp[x] Returns the Exponential of x
fabs[x] Returns the Floating Point Absolute value of x
floor[x] Round down x to the nearest whole number
ln[x] Returns the Natural Log of x
log[x] Returns the Base 10 Log of x
x%y Returns the value of x with a modulus of y
* Returns the result of the multiplication
pow[x,y] Returns the value of x raised to the power y.
Can also be represented by ^
x^y Returns the value of x raised to the power y.
recip[x] Returns the reciprocal of x (i.e. 1/x)
root[x,y] Returns the y root of x
round[x] Rounds x to the nearest whole number
sin[x] Returns the SIN of x
sinh[x] Returns the Hyperbolic SIN of x
sqrt[x] Returns the Square Root of x
sq[x] Returns the square of x (i.e. x multiply by x)
- Returns the result of the subtraction
tan[x] Returns the TANGENT of x
tanh[x] Returns the Hyperbolic TANGENT of x
