How can we access the Manage Daily Rates in groovy script

Hello Team,

We have a requirement in our current implementation like we need to convert the a currency value to different currency based on the Manage Daily Rates stored in the Application.
We thought of adding a script to do the conversion but we couldn't identify a way to access the daily rates and inversion value captured in the Manage Daily Rates for the calculation .
Please help us to identify a way for this .

Thanks,
Tinu
