Formatting big numbers in c#

daveokst asked
Last Modified: 2013-12-17
Our client is dealing with cash accounts that are in the $$$ millions.  We are using a grid to display the balances and other totals in a number of columns that span the page.  Since the columns can get narrow, the client would like large numbers to be formatted in an abbreviated way.  For example...

$25,000,000.00 would be formatted as $25.0M or something to that effect.  Is there a common formatter in the .Net framework that accommodates formatting large number in this way?


Code example preferred.

You can write your own formatprovider class.


In your formatprovider, just divide the number by 1000000, then format the result to currency and add 'M' at the end.
The closest built-in format that comes to my mind is the "e" or scientific notation format.

An example:
double value = 25000000;
string f = value.ToString("e2");
//outputs: 2.50e+007

If the client is used to looking at spreadsheets, they may be used to this sort of notation.
