Commatizing numbers: Difference between revisions

Line 11:

The number may be part of a larger (non-numeric) string such as:

::::* «US$1744 millions» ──or──

::::* «US$1744 millions»       ──or──

::::* ±25000 motes.

The string may possibly ''not'' have a number suitable for commatizing, so it should be untouched and ''no error generated''.

If any argument (option) is invalid, nothing is changed and no error ''need be'' generated (quiet execution, no fail execution). Error message generation is optional.

The exponent part of a number is never commatized. The following string isn't suitable for commatizing: 9.7e+12000

The exponent part of a number is never commatized.   The following string isn't suitable for commatizing:   9.7e+12000

Leading zeroes are never commatized. The string 0000000005714.882 after commatization is: 0000000005,714.882

Leading zeroes are never commatized.   The string   0000000005714.882   after commatization is:   0000000005,714.882

Any period in a number is assumed to be a decimal point.

Leading signs ('''+''', '''-''') are to be preserved (even superfluous signs).

Leading/trailing/imbedded blanks, tabs, and other whitespace are to be preserved. ~~E.g.: +1024 bottles of beer on the wall.~~

Leading/trailing/imbedded blanks, tabs, and other whitespace are to be preserved.

The case (upper/lower) of the exponent indicator is to be preserved. E.g.: 4.8903d-002

The character(s) to be used for the comma can be specified, and may contain blanks, tabs, and other whitespace characters, as well as multiple characters. The default is the comma (''',''')

character.

The ''period length'' can be specified (sometimes referred to as "thousands"). The ''period length'' is the length (or number) of the digits between commas. The default period length is 3.
