The decimal, when the coordinate is read by the CNC, is placed (4) places from the right ... assuming your machine is in inches. If metric ... three places from the right.
Some inch examples :
1 = .0001
20 = .0020
123456 = 12.3456
21 = .0021
Your example is a Fanuc program ... just FYI, some machines will read the value of say X1 as X 1.0000" ... but most Fanuc machines are set up so that X1 actually means X.0001".
Hope this helps ....
