Soft key Linking function
Arc tangent
Inverse function of the tangent; determine the
angle
from the ratio of the opposite side to the
adjacent side
e.g.
Q12 = ATAN Q50
Powers of values
e g.
Q15 = 3^3
Constant Pl (3.14159)
e.g.
Q15 = PI
Logarithmus Naturalis (LN) of a row
Base 2.7183
e.g.
Q15 = LN Q11
Logarithm of a number, Base 10
e. g.
Q33 = LOG Q22
Exponential function, 2.7183 to the power
of n
e. g.
Q1 = EXP Q12
Negate values (multiply by -1)
e.g.
Q2 = NEG Q1
Truncate digits after the decimal point
Form an integer
e.g.
Q3 = INT Q42
Absolute value of a number
e. g.
Q4 = ABS Q22
Truncate digits before the decimal point
Form a fraction
e.g.
Q5 = FRAC Q23
Check algebraic sign of a number
e g
Q12 = SGN Q50
When return value Q12 = 1, then Q50 >= 0
When return value Q12 = -1, then Q50 < 0
Calculate modulo value (division remainder)
e. g.
Q12 = 400 % 360
Result: Q12 = 40
