Strings

There real isn't any formatting within a strong, beyond it's alignment. Alignment works for any argument beingprinted in a string.format call.

SamplegeneratsString.format ("-> {1, 10} <-", "hello"); -> hello <-string.format ("-> {1, -10} <-", "hello"); -> Hello <-

Numbers

Basic Number Formatting Specifier:

Custom Number Formatting:

EEXPONENT PlaceHolder {0: 00e 0} 15e 2MANY Exponent Formats Available.; Group SeparatorSee Below

The group separator is especially useful for formatting currency values ​​which require that negative values ​​be enclosed in parentheses This currency formatting example at the bottom of this document makes it obvious:. Dates

............................... ...CRIPLILE, TELEGEMENCE.

The 'u' Specifier Seem Broken; That String Certainly isn't Sortable.

Custom Date Formatting:

Some useful exampletring.format ("{0: $ #, ## 0.00; ($ #, ## 0.00); zero}", value);

This Will Output "$ 1,240.00" if passed 1243.50. It will output the Same Format But in Parentheses if The number is negative, and will output the string "zero" if the number is zero.

String.Format ("{0: (###) ### - ####}", 18005551212);

THIS WILL OUTPUT "(800) 555-1212".
