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
Calculate the natural logarithm of a number
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
Remove digits after the decimal point
Calculate an integer
e.g.,
Q3 = INT Q42
Absolute value of a number
e.g.,
Q4 = ABS Q22
Remove digits before the decimal point
Calculate a fraction
e.g.,
Q5 = FRAC Q23
Check algebraic sign of a number
e.g.,
Q12 = SGN Q50
When return value Q12 = 0, then Q50 = 0
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
