7 Programming with Q Parameters
7.2 Describing Contours Through Mathematical Functions
Overview
The mathematical functions assign the results of one of the following
operations to a Q parameter:
D00: ASSIGN
e.g. N10 D00 Q05 P01 +60 *
Assigns a value directly
D01: ADDITION
e.g. N10 D01 Q01 P01 –Q2 P02 –5 *
Calculates and assigns the sum of two values
D02: SUBTRACTION
e.g. N10 D02 Q01 P01 +10 P02 +5 *
Calculates and assigns the difference between two values
D03: MULTIPLICATION
e.g. N10 D03 Q02 P01 +3 P02 +3 *
Calculates and assigns the product of two values
D04: DIVISION
e.g. N10 D04 Q04 P01 +8 P02 +Q02 *
Calculates and assigns the quotient of two values
Note: Division by 0 is not possible!
D05: SQUARE ROOT
e.g. N10 D05 Q20 P01 +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.
