is an option for NumberForm and related functions that specifies the maximum length of blocks of digits between breaks.

Details

  • The default setting is DigitBlock->Infinity, which specifies that no breaks should be inserted.
  • DigitBlock->n inserts a break every n digits. »
  • DigitBlock->{nleft,nright} inserts a break every nleft digits to the left of the decimal point, and every nright digits to the right of the decimal point. »
  • The setting for NumberSeparator determines what string should be used at each break. »
  • DigitBlock can also be used to specify what to assume for interpretation of numbers with Interpreter["Number",…].
