So the choice of how to dump is basically arbitrary, but I think the basic reasoning is that:</div><div> - we want to print as decimal, because the most important cases are small positive numbers, and printing those in hex would be obnoxious</div><div> - small negative numbers all look like each other when they've been printed as their unsigned equivalents</div><div> - large unsigned numbers are usually bitmasks anyway, so the mere act of printing them in decimal will already obscure their meaning</div><div><br></div><div>John.</div></div></body></html>
