419 The CTRL-A and CTRL-X commands work for (signed) decimal numbers, unsigned 419 The CTRL-A and CTRL-X commands can work for:
420 octal and hexadecimal numbers and alphabetic characters. This depends on the 420 - signed and unsigned decimal numbers
421 'nrformats' option. 421 - unsigned binary, octal and hexadecimal numbers
422 - alphabetic characters
423
424 This depends on the 'nrformats' option:
425 - When 'nrformats' includes "bin", Vim assumes numbers starting with '0b' or
426 '0B' are binary.
422 - When 'nrformats' includes "octal", Vim considers numbers starting with a '0' 427 - When 'nrformats' includes "octal", Vim considers numbers starting with a '0'
423 to be octal, unless the number includes a '8' or '9'. Other numbers are 428 to be octal, unless the number includes a '8' or '9'. Other numbers are
424 decimal and may have a preceding minus sign. 429 decimal and may have a preceding minus sign.

448 zeros cause mistakes, because they can be confused with octal numbers. 453 zeros cause mistakes, because they can be confused with octal numbers.

455 Note similarly, when 'nrformats' includes "bin", binary numbers with a leading
456 '0x' or '0X' can be interpreted as hexadecimal rather than binary since '0b'
457 are valid hexadecimal digits.
