[esp-r] Re: Automatic rounding of decimal points - locale settings

[Marco Manzan]

hi to all,

the problem of comma separated decimals is shared among all platforms linux too and is related to GTK libraries. If esp-r is compiled against X11 (the mode I prefer)  the numbers are always stored with dot-decimal notations. otherwise, if the gtk version is used it is a dangerous process since, as explained by Jon Hand, the data file get messed up. So if you use comma separated decimals in internationalization features of your desktop, for instance I use Italian, you have to be sure to reset the decimal notation before starting esp-r. In the linux bash shell I set    "export LC_NUMERIC=en_EN". For instance a number of software require the dot-decimal notation  also in windows, an example is GSLedit for complex fenestration proprieties definition.

I hope this helps

My recent experience with students is that either a Cygwin installation or a dual boot Linux installation was basically manageable by the students (one, each, only, though, so no large statistic). Being able to compile the code does make life easier, in my experience.
