Re: [fpc-devel] Format with zero padding

Wouldn't this be useful for FPC's Format as well, or is there another way ? in fpc it's a dot.

I did read that page, but only saw 'padded with spaces' and assumed Precision was only applicable to floating point values, as it's after the dot.

As if format strings were intuitive at all. :-) I'd call Zero_Pad (Some_Int, 4) definitely more intuitive. Seriously, isn't Format an imitation of C's printf ? Apart from the fact, that you can get run time type checking? Yeah, I suppose so. At least they are very similar, but on this detail (and maybe some others as well) they are different. Well, let's assume it's due to Delphi-compatibility. Probably Borland decided to do it differently just for the fun of it. ;-) Vinzent. ___ fpc-devel maillist - fpc-devel@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-devel

SysUtils.Format ('%.4D', Some_Int); Sounds like I found a case where 'C' is more intuitive than pascal ;-). With a C mindset, yes. There a leading 0 can have meaning. In Pascal an extra leading zero never has meaning. Seriously, isn't Format an imitation of C's printf ?

Ah well, maybe in C07 that will be fixed. ___ fpc-devel maillist - fpc-devel@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-devel

In Pascal an extra leading zero never has meaning. It's a formatting string, not a number only. You think a digit *after* the decimal point to be used for integers in front of the whole number is more intuitive ?

You think a digit *after* the decimal point to be used for integers in front of the whole number is more intuitive ? Perfect? no. Better than leading 0? yes. Leading zeroes that have meaning are an artificial construct. Keep in mind that C users might be aware of deviant use (they are octal numbers as literals), but Pascal users most probably wouldn't think twice. ___ fpc-devel maillist - fpc-devel@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-devel
