As its original author, I am not clear that this is a good use of
-tostring-, but its -format()- option offers in principle what you
seek.

You might get better advice if you said more about the data and quite
how this strange situation occurs. The bottom line is that what you
intend to do with the variable should have most influence on how it is stored.

At the moment I'm having real difficulty imagining a measurement
process that yields 45 digits. Is there a decimal point? Are these
"numbers" just identifiers of some kind?
