Standard numeric format strings can be used to format common numeric types in the client browser. A standard numeric format string takes the form Axx, where A is an alphabetic character called the format specifier, and xx is an optional integer called the precision specifier. The precision specifier ranges from 0 to 99 and affects the number of digits in the result. Any numeric format string that contains more than one alphabetic character, including white space, is interpreted as a custom numeric format string.

Below is a list of supported standard format strings. The format string can be specified either directly or in curly brackets. The currency format string from the example can be written as “C4” or “{0:C4}”.
