You can use numeric formatting characters to display numbers in particular formats. These formats work with a variable's ToString method as well as with String.Format. For example, the code value.ToString("C") returns the variable value formatted as currency.

The following table shows the standard numeric format characters.

Floating Point Formats
Name	Format Character	Example
Currency	C or c	($12,345.68)
Exponential	E or e	-1.234568E+004
Fixed Point	F or f	-12345.68
General	G or g	-12345.6789
Number	N or n	-12,345.68
Percent	P or p	-1,234,567.89 %
Round-trip	R or r	-12345.6789
