DigitBlock

DigitBlock
is an option for NumberForm and related functions that specifies the maximum length of blocks of digits between breaks.
  • The default setting is DigitBlock->Infinity, which specifies that no breaks should be inserted.
  • DigitBlock inserts a break every nleft digits to the left of the decimal point, and every nright digits to the right of the decimal point. »
Separate integer digits in blocks of 3:
Separate real digits in blocks of 2:
Use three-digit blocks on the left of the decimal and two-digit blocks on the right:
