Operands
Operands can be:
•
Constants
•
System constants
•
NC variables
•
Address letters, and
•
Functions
Floating decimal point constants can be comprised of the following ele-
ments:
•
Sign of the mantissa
•
Up to 6 decimal places
•
Number of places to the left of the first through sixth decimal digit
•
Exponent symbol "E"
•
Sign of the exponent, and
•
Up to 2 decimal places for the exponent
In order for the use of internal floating decimal point calculations, the
decimal point or the exponent sign must be present.
Example of legal floating-decimal-point constants
-0.
+123456.
1E0
-123456E+1
0.1E-00
+100.000E12
The decimal numerical value statements is interpreted as an integer con-
stant, both without the decimal point and without the exponent. Integer
constants can optionally consist of a sign and up to ten decimal places.
Example of legal integer constants

The circle number "PI" (3.14159265...) and the conversion factor to go
from the inch system to the metric "KI" system (25.4) are available for use
as system constants which are programmed using their symbolic names.
Because of their higher internal accuracy, these constants should always
be used.
