psilwen,

Are you suggesting that newLISP allow the user to enter a number of arbitrary length (as input) and then parse and store the internal representation of the number (as an exact representation of the input, i.e. arbitrarily large)?

AFAIK, no programming language allows this. There are always limits. Life is about dealing with "scarce" resources, and one of the major issues of software design is how to deal with that scarcity, while still meeting the goals you have in mind.

Given that, what do you propose should be the design for entering and storing numbers in newLISP? Curious.

and costly for code size and speed. newLISP would be slower and much bigger when designed in this philosophy. I doubt the splitting of large floats would ever occur with a 255(*) size limit.
