Linear equation
A=E1⋅ E2 + E3
tanα = E2 = A/E1
Default A = E1 ⋅ E2
Natural logarithmer
A = In E1 E1 > 0
E1 ≤ 0, A = --10
19
Multiplier
A=E1⋅ E2 ⋅ E3; with default: A = E1 ⋅ E2
Exponential function
A=E1⋅ E2
E3
A=e
E3
(default)
Rooter
A =

E1

The equation
only applies for
positive E1, ne-
gative E1 are
set equal to
zero. The output
can be set to
zero with E2 for
lower values of
E1, i.e.
A=0forE1 ≤
E2
Subtractor
A = E1 -- E2 -- E3; with default: A = --E2
With the default, this function acts as a negation for E2
