# DigitBlock

 DigitBlockis 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:
Separate integer digits in blocks of 3:
 Out[1]//NumberForm=

Separate real digits in blocks of 2:
 Out[1]//NumberForm=

Use three-digit blocks on the left of the decimal and two-digit blocks on the right:
 Out[1]//NumberForm=
 Scope   (5)
Specify spaces as separators:
Use commas as separators on the left and no separators on the right:
Use different block sizes and separators on the left and right:
