PT Program Generator (PPG) v5.0
For example, you could multiply the contents of the default register by 3 and
store the results in a register called
Triple
. Rather than supplying a constant
(such as 3), you could specify another register that contains the number you
want to multiply, add, subtract, or divide by.
Figure 45 on page 69
shows the dia-
log box for a
Math
node.
The format of the math function is as follows:
Constant | Register | File + | - | / | *|
% Constant | Register = Register | File
The results of the math operation must be within the range of
-999,999,999
through
999,999,999
and are always rounded to the
nearest integer.
Floating Point Math
PPG supports floating point math. Decimal values and exponential notation
of values with up to 13 digits can be entered in an application.
Operand 1 Tab
The
Operand 1
tab lets you specify a constant value or a file or register con-
taining the first operand for the mathematical operation. The location of
Operand 1
is displayed near the bottom of the dialog.
