Short code for dollar value in text

The plugin has some shortcode or some way to update the price of the dollar according to the rate that I indicate.

But not in the product, but that I have a notice that says the dollar rate today is 24.34, but when the rate changes, that I change it in the multi currency to update the price of products also do so in that announcement.

Additionally it is possible for the plugins to update the value of a formula with the price of the dollar you have in multi currency.

For example I have a calculator on the site with the plugins Calculated Fields Form to the plugins I put a formula for the calculation, however it is possible that the value of the calculation that refers to the price of the dollar, Multi Currency gives it to the plugins of Calculated.

To automate the process.
