(...) Thanks for the info. I've always used perl scripts to convert oddly formatted data to a consistent format and then read it like that. Nice to know I don't always have to.

(...) All float specifiers (e, E, f, g, G) are treated identically by the scanf functions. When scanning floats, they always recognize all float formats. One other thing about %g on output is that it automatically strips trailing zeros, which %f (...) (15 years ago, 12-Mar-10, to lugnet.cad.dev)

(...) Ahhh. I'd never heard of %g before now. I'm so used to %f and %e it had never occured to me that there might be a mixed option. Handy to know as I suspect it would be helpful in reading files of unknown format. I'm sure Delphi has some hideous (...) (15 years ago, 12-Mar-10, to lugnet.cad.dev)

(...) Actually, in C, %g does exactly this. Having said that, I think LDDP is a Delphi app, so it uses Pascal, and I don't remember how Pascal does formatting. --Travis (15 years ago, 12-Mar-10, to lugnet.cad.dev)

(...) My suggestion would be to read numbers in that notation but never write them. I'm not sure why LDDP would write them that way (it would require some strange output routines) but if one thing writes them then it's best to read them. Tim (15 years ago, 11-Mar-10, to lugnet.cad.dev)
