Excellon drill files are a very old variant of RS-274D.  
They use suppressed decimal points and suppressed trailing 
decimals.  So, no way will LinuxCNC read them as is.  So, if 
the format is 2.3, then an X coordinate of 1.2345 will be 
X01234, and a coordinate of 1.2 will be X012.

But, it is simple to write a program that reparses this stuff.
