In Mathematica 7.0.1, from the menu select Edit > Preferences. Select the Appearance tab and then its Numbers tab. On the Formatting tab there, you'll see an option "Digit block separator". You may change that to a thin comma, a comma, or a period. The same option may be set directly in the Options Inspector. Search for NumberSeparator there. If you change from the default, \[ThinSpace], you can opt to set this just for the current selection, just for the current notebook, or globally. underante wrote: > hello, > > in Mathematica v4 and 5.2 to print long numbers separated by commas in blocks > of 3, i used to use something like this for example: > > NumberForm[N[Pi, 10], DigitBlock -> 3] > > which gave: > > 3.141,592,654 > > i.e. commas to the right of the decimal point. but in Mathematica v7.0.1 the > same statement generates number blocks separated by spaces, i.e: > > 3.141 592 654 > > i can recover the commas by using something like: > > NumberForm[N[Pi, 10], DigitBlock -> 3, NumberSeparator -> ","] > > but does anyone know if there is a quick fix to get the old style > commas back without having to change all my old programs in this way? > > thankyou, > > f.c. > -- Murray Eisenberg murray at math.umass.edu Mathematics & Statistics Dept.
