1.5.7.2 Mathematical Functions
Absolute value
A=|E1|
Adder
A = E1 + E2 + E3
with default: A = E1 + E2
Divider
A=E1/E2
with default: A = 1/E2
Definitions:
0/number = 0, 0/0 = 0,
number/0 = 10
19
E2 can be limited by E3. This pre-
vents the output jumping between
+10
19
and --10
19
at lower values of E2
(about 0) and becomes very rest-
less due to the great steepness. If you
do not want this limit, E3 must be as-
signed 0.000.
E3 > 0
Minimum value limiting of E2 to the
value of E3 (division only in the 1st
and 4th quadrants).
E3 < 0
MaximumevaluationofE2tothe
value of E3 (division only in the 2nd
and 3rd quadrants).
E3 = 0
No limiting of E2 (division in all 4
quadrants with pole position at
E2 = 0).
Decadic logarithmer
A = lg E1 E1 > 0
E1 ≤ 0, A = --10
