350 The CTRL-A and CTRL-X commands work for (signed) decimal numbers, unsigned 350 The CTRL-A and CTRL-X commands work for (signed) decimal numbers, unsigned
351 octal and hexadecimal numbers and alphabetic characters. This depends on the 351 octal and hexadecimal numbers and alphabetic characters. This depends on the
352 'nrformats' option. 352 'nrformats' option.
353 - When 'nrformats' includes "octal", Vim considers numbers starting with a '0' 353 - When 'nrformats' includes "octal", Vim considers numbers starting with a '0'
354 to be octal. Other numbers are decimal and may have a preceding minus sign. 354 to be octal, unless the number includes a '8' or '9'. Other numbers are
355 decimal and may have a preceding minus sign.
355 If the cursor is on a number, the commands apply to that number; otherwise 356 If the cursor is on a number, the commands apply to that number; otherwise
356 Vim uses the number to the right of the cursor. 357 Vim uses the number to the right of the cursor.
357 - When 'nrformats' includes "hex", Vim assumes numbers starting with '0x' or 358 - When 'nrformats' includes "hex", Vim assumes numbers starting with '0x' or
358 '0X' are hexadecimal. The case of the rightmost letter in the number 359 '0X' are hexadecimal. The case of the rightmost letter in the number
359 determines the case of the resulting hexadecimal number. If there is no 360 determines the case of the resulting hexadecimal number. If there is no

365 For numbers with leading zeros (including all octal and hexadecimal numbers), 366 For numbers with leading zeros (including all octal and hexadecimal numbers),
366 Vim preserves the number of characters in the number when possible. CTRL-A on 367 Vim preserves the number of characters in the number when possible. CTRL-A on
367 "0077" results in "0100", CTRL-X on "0x100" results in "0x0ff". 368 "0077" results in "0100", CTRL-X on "0x100" results in "0x0ff".
369 There is one exception: When a number that starts with a zero is found not to
370 be octal (it contains a '8' or '9'), but 'nrformats' does include "octal",
371 leading zeros are removed to avoid that the result may be recognized as an
372 octal number.

369 Note that when 'nrformats' includes "octal", decimal numbers with leading 374 Note that when 'nrformats' includes "octal", decimal numbers with leading
370 zeros are impossible because they are indistinguishable from octal numbers. 375 zeros cause mistakes, because they can be confused with octal numbers.
