I don't think that this "implied" applies in my experience to pretty 
much all programming languages that I have used in the last 47 years 
that do offer various forms of floating point formats.
Not specifying in a program, specially in a strict programming language 
like Pascal, will always result in implementation depending 
variations/assumptions.

And if those variations are not to your liking, then simply specify 
(type cast) those constants to more precisely get the result you expect. 
This is Pascal after all, not Python or other over-ooped programming 
language that is making assumptions about your code all the time...
