Thanks Jacque, a gold mine of information as usual. But it’s pretty obscure, isn’t it? All this started for me because I wanted to test if two numbers were equal, knowing that they probably weren’t exactly equal to the last decimal place but nevertheless were ‘engineering equal’ as it were - say to six places of decimals. So I tried to truncate them to that length and then compare them. More fool me. But now I think I know what should be done, thanks to you - and to everyone else who replied.
