how to calulate the digits in column of x and y utm coordinates before the decimal point

Use a SubstringExtractor to pull out the digits before the decimal point:

 

Start index: 0

 

End index: @FindString(@Value(x-coord),.)-1

 

x-coord is your x attribute, . is what you're looking for and -1 to get the position one step to the left of the decimal point.

Then use a Tester to check that the resulting string isn't too long:

 

@Evaluate(@StringLength(@Value(_substring))) < 7

 

_substring is the string you just pulled out with the SubstringExtractor.

You can use the Tester to test if the value is less than 1000000 (i.e. the minimum value of 7 digits).

Doh. Sometimes the answer is just too obvious. :-) In my defense, I'm busy at work with the same maneuver but with character strings, so that's where my head is at the moment.
