Decimal point programming

There are two notations for the interpretation of programming values without a
decimal point in ISO Dialect mode:
S pocket calculator type notation
Values without decimal points are interpreted as mm, inch or degrees.
S standard notation
Values without decimal points are multiplied by a conversion factor.
The setting is defined by MD 10884.
There are two different conversion factors, IS-B and IS-C. This evaluation refers to
addresses X Y Z U V W A B C I J K Q R and F.
Example of linear axis in mm:
X 100.5
X 1000
