Hi,

My name is André Lopes and i am writing from Brazil.
I have a big problem and i am nedding help ...
I have in a cell (For example "A2") the following:

"Este é um teste e a taxa do USD é USD - 1.667"

And i need to extract only the value that will be, ever, *.***, where *
means any number.
Please note that i never know what will be the number of digits in the cell,
being that the value could have digits after it too.
