string value to be displayed in number format

Hi All,

I am facing one problem when i am displaying a negative number in output.I have a number 123,567,90.89-.They want the sign should be on left-side.I did that shifting the sign to left by passing that value into one string type variable.But when i copied the value into string symbol ',' is ommiting and the value is getting stored as '12356790.89-',But i have to display the value in such a way that sign should be in left-side and it should be in number format.i.e,

-123,567,90.89.

Please give me a solution to resolve this problem..

With Regards,
