7.2 Describing Contours Through Mathematical Functions
Overview
The mathematical functions assign the results of one of the following
operations to a Q parameter:
FN0: ASSIGN
e.g. FN0: Q5 = +60
Assigns a value directly
FN1: ADDITION
e.g. FN1: Q1 = –Q2 + –5
Calculates and assigns the sum of two values
FN2: SUBTRACTION
e.g. FN2: Q1 = +10 – +5
Calculates and assigns the difference between two values
FN3: MULTIPLICATION
e.g. FN3: Q2 = +3 ❊ +3
Calculates and assigns the product of two values
FN4: DIVISION
e.g. FN4: Q4 = +8 DIV +Q2
Calculates and assigns the quotient of two values
Note Note Note Note Note: Division by 0 is not possible!
FN5: SQUARE ROOT
e.g. FN5: Q20 = SQRT 4
Calculates and assigns the square root of a number
Note: Square root of a negative number is not possible!
The “values” in the overview above can be:
• two numbers
• two Q parameters
• a number and a Q parameter
The Q parameters and numerical values in the equations can be entered
with positive or negative signs.
To select a mathematical operation
FN0: ASSIGN
Select function directly or with arrow keys,
e.g. FN3: MULTIPLICATION.
FN3: MULTIPLICATION
Open a new block with the function FN3: MULTIPLICATION.
