I don't remember exactly, but if you check the block definition for X, Y and Z coordinates, you will find the solution.
What is the reason for removing the decimal point?
You may already be aware of this but be careful as I'm fairly sure that some controllers rely on the decimal point to differentiate between, for example, millimeters and microns.
E.g. X175. will be read as 175mm
X175 will be read as 175 microns.
The question became from the programmers who are now manually programming the machines.
They found it confusing.
If you do things manually you try to avoid as much typing as possible.
The NC code is created by the computer, so change as less as possible. The machine operators don't have to change these files manually, so don't change it if the machine is happy with it.

NX Customization - Best Practice Guide
If the decimal point is causing no issue with the machine I would suggest you leave it as it is.
There is a way of achieving what you want and rather than echo it here I will link you to another thread where this question was asked. The solution was to add custom code to the beginning of the post processor....
As is mentioned in the above thread, this solution will increase processing time when posting and may open you up to errors in certain situations. Any (even slight) errors when playing with decimal points in machine code can be disastrous for obvious reasons.
If it was me, I would leave it as is and would explain to your programmers the risk that is involved in this sort of customisation and that the con's far outweigh the pro's in this instance.
No, not the data definitions as this will only work if your value is 0.
On page 2 of the thread, the third post down, written by 'Postino' is the custom code i am talking about.
