Square and root calculations

Hi,

Thanks for creating this great plugin. Probably I am going to ask something a little bit weird but I need it for my price calculations.

Is there any way to use square and/or root calculations in the plugin formula field?

The only way I figure out to increase the price in a logarithmic way is by using their operations. In other words, the higher the value entered by the customer, the lower the increment in price.

Thanks a lot!
