multiplication

What in the world am I doing wrong?

 

$percentFormat is 0.093.

$totalExpenses is 1,113,451.00.

 

$numAdminCost = ($percentFormat * $totalExpenses);

 

$numAdminCost ends up being 0.093.  I've googled this and tried some different solutions but am not having any luck.  I'm sure there is a bonehead error somewhere.

 

Please and thanks.

The thousands comma separators are a human convention to make numbers easier to read and have no meaning to a computer when used in a number. Well actually they do have some meaning, they are a stop-character, i.e. a character that is not a numeric digit or a decimal point.

 

A computer sees your example as .093 * 1(stop-character) which equals .093

 

You will need to remove any commas from numbers if you want a computer to operate on that number.
